The '''MG 42''' (shortened from German: ''Maschinengewehr 42'', or "machine gun 42") is a [[Nazi Germany|German]] recoil-operated air-cooled [[general-purpose machine gun]] used extensively by the ''[[Wehrmacht]]'' and the ''[[Waffen-SS]]'' during the second half of [[World War II]]. Entering production in 1942, it was intended to supplement and replace the earlier [[MG 34]], which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II.

Designed to use the standard German [[fully powered cartridge|fully-powered]] [[7.92×57mm Mauser]] rifle round and to be cheaper and easier to manufacture, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges: it averaged about 1,200 rounds per minute, compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the [[M1919 Browning machine gun|M1919 Browning]], [[FM 24/29 light machine gun|FM 24/29]], or [[Bren light machine gun|Bren gun]]. This made it extremely effective in providing [[suppressive fire]]. Its unique sound led to it being nicknamed "Hitler's buzzsaw".<ref name="SAOTH-10th">{{cite book|last1=Smith|first1=Joseph E.|title=Small Arms of the World|date=1973|publisher=Stackpole Co.|location=Harrisburg, PA, USA|edition=10th}}</ref>

The MG 42 was adopted by several armed organizations after the war, and was both copied and [[Licensed production|built under licence]]. The MG 42's lineage continued past Nazi Germany's defeat, forming the basis for the nearly identical ''MG1'' (MG 42/59), chambered in [[7.62×51mm NATO]], which subsequently evolved into the MG1A3, and later the {{Lang|de|[[Bundeswehr]]|italic=no}}'s [[Rheinmetall MG 3|MG 3]], Italian [[:it:Beretta MG 42/59|MG 42/59]], and Austrian [[#MG 74|MG 74]]. In [[Yugoslavia]], an unlicensed, near-identical copy was produced as the [[Zastava Arms|Zastava]] [[#M53|M53]].

The MG 42 lent many design elements to the Swiss [[MG 51]] and [[SIG MG 710-3]], French [[AA-52]], American [[M60 machine gun|M60]], the Belgian [[FN MAG|MAG]] general-purpose machine guns, and the Spanish [[5.56×45mm NATO]] [[CETME Ameli|Ameli]] [[light machine gun]].

==History==
===Before World War I===
Even before [[World War I]], the German military was already looking forward to replacing the heavy machine guns which proved to be such a success in that war. The [[MG 13|MG13]] was one of the first developments toward a goal of producing a weapon that could perform multiple roles, rather than just one. The MG13 was the result of reengineering the Dreyse Water-cooled machine gun to fit the new requirement.<ref name="SAOTH-10th" /> The twin-barreled [[Gast gun]] was developed with the goal of providing a high cyclic [[rate of fire]] weapon for anti-aircraft use which was reported to have reached cyclic rates of fire as high as 1,600 rounds per minute.<ref name="SAOTH-10th" />

===1930s===
[[File:German Machine Gunner (7527779440).jpg|thumb|left|Wehrmacht [[Historical reenactment|reenactors]] with an MG 34 general-purpose machine gun mounted on a ''Lafette 34'' tripod]]

This eventually led to the ''Einheitsmaschinengewehr'' (Universal machine gun) introducing an entirely new concept in automatic firepower. By changing its mount, sights and feed mechanism, the operator could radically transform an ''Einheitsmaschinengewehr'' for several purposes.

The [[MG 34]] is considered to be the first modern [[general-purpose machine gun]] or ''Einheitsmaschinengewehr''. It was developed to use the standard German 7.92×57mm Mauser full-power rifle round.<ref name="SAOTH-10th" /> It was envisaged and well developed to provide portable [[Light machine gun|light]] and [[medium machine gun]] infantry cover, low level anti-aircraft coverage, and even sniping ability. Equipped with a quick-change barrel and fed either with [[Belt (firearms)#Non-Disintegrating Belt|non-disintegrating metallic-link belts]], or from a 50-round ''Gurttrommel'' (belt drum) or a 75-round spring-loaded [[Drum magazine|saddle-drum]] ''Patronentrommel 34'' magazines (with a simple change of the feed cover for a Trommelhalter magazine holder), the MG 34 could sustain fire for much longer periods of time than other portable [[Squad automatic weapon|squad-level weapons]] such as the American [[M1918 Browning Automatic Rifle]] (BAR), Soviet [[Degtyaryov machine gun]] (DP-27) and the British [[Bren light machine gun|Bren gun]], which were fed by [[Magazine (firearms)|magazines]], while also being much lighter and more portable than crew-served weapons like the [[M1919 Browning machine gun|Browning M1919]], [[SG-43 Goryunov]] or [[Vickers machine gun|Vickers]] machine guns (which also lacked quick-change barrels). The MG 34 was also quite versatile; not only was it able to be fed from belted ammunition or a saddle drum magazine, it could also be fired from a bipod, an innovative ''Lafette 34'' [[tripod]] or various pintle mounts for armored vehicles. Switching between a bipod and a tripod required no special tools, as the mounting latch was spring-loaded. As the '''MG 34 ''Panzerlauf''''', it was used throughout the war as secondary armament on [[panzer]]s and other vehicles.

However, the MG 34 did have fundamental drawbacks, such as sensitivity to extreme weather conditions, dirt and mud, and comparatively complex and expensive production. Attempts to incrementally improve the basic MG 34 design failed.<ref>{{cite book|last1=Smith|first1=W.H.B.|title=Small Arms of the World|date=1973|publisher=Stackpole|pages=437–442|edition=10th}}</ref>{{sfn|McNab|2012|p=17}}

Between 1934 and the adoption of the final MG 34 production version, the ''[[Waffenamt]]'' (German Army Weapons Agency) realized the MG 34 ''Einheitsmaschinengewehr'' was too complex and expensive to [[mass production|mass-produce]] and started looking for ways to simplify and rationalize the technical concept.

===Development of the MG 42===
[[File:Bundesarchiv Bild 146-1983-109-14A, Frankreich, MG-Schütze.jpg|thumb|left|A ''[[Waffen-SS]]'' soldier in 1944 carrying an MG 42 configured as a light support weapon with a folding bipod and  50-round basket drum containing the ammo belt.]]

A draft specification was made and a contest was held for an MG 34 replacement. Three companies were asked in February 1937 to submit designs: Metall und Lackierwarenfabrik Johannes Großfuß AG of [[Döbeln]], [[Rheinmetall|Rheinmetall-Borsig AG]] of [[Sömmerda]], and Stübgen AG of [[Erfurt]].<ref name="Willbanks">Willbanks, James: ''Machine Guns: An Illustrated History of Their Impact'', page 115. ABC-CLIO, 2004.</ref> The design and mock-up gun proposals were submitted in October 1937.<ref>{{Cite web |title=Dead End: MG 39 Rh |url=http://www.forgottenweapons.com/dead-end-mg-39-rh/ |archive-date=15 June 2013 |archive-url=https://web.archive.org/web/20130615093647/http://www.forgottenweapons.com/dead-end-mg-39-rh/ |publisher=Forgottenweapons.com |date=19 December 2012 |access-date=2013-06-19}}</ref> Großfuß AG's entry proved to be the best design by far, employing a unique [[Recoil operation|recoil-operated]] [[Roller locked|roller locking]] mechanism whereas the two competing entries used a [[Gas-operated reloading|gas-actuated]] system.<ref name="Willbanks"/> The Großfuß company had no earlier experience in weapons manufacture, specializing in pressed and stamped steel components (the company's staple product was [[sheet metal]] [[lantern]]s). Dr.-Ing. [[Werner Gruner]], one of the leading design engineers with Großfuß, knew nothing about machine guns when he was given the task of being involved with the project, although he specialized in the technology of mass production. [[:de:Werner Gruner|Gruner]] would attend an army machine gunner's course to familiarize himself with the utility and characteristics of such a weapon, also seeking input from soldiers. He then recycled an existing [[Mauser]]-developed operating system and incorporated features from his experiences with army machine gunners and lessons learned during the early stages of the war.<ref name="Willbanks"/>

Being made largely out of [[Stamping (metalworking)|pressed and stamped]] appropriately hardened [[carbon steel]] metal, only the most important parts were elaborately milled from solid steel, and using [[spot welding]] and riveting to connect parts the new design required considerably less machining and fewer high grade [[alloy steel|steel alloys]] containing metals that became scarce in Germany during World War II.<ref>[http://www.lonesentry.com/manuals/german-infantry-weapons/mg42-machine-gun.html German Infantry Weapons U.S. War Department  Military Intelligence Service, Special Series No. 14, May 25, 1943]</ref> It was much simpler to build than other machine guns&nbsp;– it took 75 [[man hour]]s to complete the new gun as opposed to 150 man hours for the MG 34 (a 50% reduction), {{convert|27.5|kg|lb|abbr=on}} of raw materials as opposed to {{convert|49|kg|lb|abbr=on}} for the MG 34 (a 44% reduction)&nbsp;– and cost 250 [[German reichsmark|RM]] as opposed to 327 RM (a 24% reduction).

The initial trials of the Großfuß functional model presented in April 1938 gave rise to improvement requests by the machine gun contest board. The resulting Großfuß '''MG 39''' prototype gun presented in February 1939 remained similar to the earlier MG 34 overall, a deliberate decision made to maintain familiarity and capability to use the various mounts and other accessories developed for the MG 34 to adapt the gun to different roles. The only major changes from the gunner's perspective were dropping of the saddle-drum-magazine feed option, leaving the weapon to fire [[Belt (firearm)|belted ammunition]], or from a single 50-round drum-shaped ''Gurttrommel'' belt container fitted to the gun's receiver, and simplifying the weapon's [[Iron sights|open sights]] for aiming purposes. All these changes were intended to increase, maintain, or accommodate the gun's high cyclic rate of fire and dispersion. Although made of relatively inexpensive and simple parts, the prototypes proved to be considerably more rugged and resistant to jamming than the precisely machined and somewhat temperamental MG 34. Further trials resulted in selecting the Großfuß MG 39 prototype gun for final production development. A limited run of about 1,500 of further improved '''MG 39/41''' pre mass-production model guns, was completed in 1941 and by the end of 1941 tested in combat trials.

===Adoption of the MG 42===
In early 1942 the final model of the weapon was officially accepted, and manufacturing of the mass-production model began, as the '''MG 42''', contracts going to [[:de:Metall- und Lackwarenfabrik Johannes Großfuß|Großfuß]], [[Mauser-Werke]], [[Simson (company)#1934–48|Gustloff-Werke]], [[Steyr-Daimler-Puch|Steyr]] and others. The MG 42 was first deployed in May 1942 by the ''[[Afrika Korps|Deutsches Afrikakorps]]'' (German Africa Corps expeditionary force in Africa) and introduced by mid-1942 on all fronts. Production during the war amounted to over 400,000 units (17,915 units in 1942, 116,725 in 1943, 211,806 in 1944, and 61,877 in 1945).<ref name="Folke Myrvang 2003"/>

In 1943, MG 42 production surpassed MG 34 production and continued to do so until the end of the war. The Germans nevertheless continued widespread production of MG 34s in parallel until the end of the war.{{sfn|Haskew|2012|p=85}}

===MG 42 nicknames===
The distinctive sound caused by the high cyclic firing rate gave rise to a variety of nicknames. The Germans called it the ''Hitlersäge'' ([[Hitler]]'s Buzzsaw), ''Schnelle Spritze'' (Fast Sprayer), ''Knochensäge'' (Bone Saw), ''Tripperspritze'' (Gonorrhoea Syringe) and ''elektrisches MG'' (Electric MG). The Soviets called it the "Linoleum Ripper", and British and American troops called it "Hitler's [[Buzzsaw]]", or "Hitler's [[Zipper]]".{{sfn|McNab|2012|p=62}} Like the MG 34, British troops sometimes called it a "Spandau", a traditional generic term for all German machine guns, left over from the famous Allied nickname for the [[MG 08]] [[Maxim gun|Maxim]]-derivative used by German forces during World War I and derived from [[Deutsche Waffen und Munitionsfabriken|its manufacturer]]'s plates noting the city of [[Spandau]] where some were produced.<ref>{{cite web|author=Michael Duffy |url=http://www.firstworldwar.com/atoz/mgun_spandau.htm |title=Encyclopedia - Spandau Gun |website=Firstworldwar.com |date=2009-08-22 |access-date=2016-12-08}}</ref> [[Brazilian Expeditionary Force|Brazilian expeditionary soldiers]] fighting in Italy used to refer to the MG 42 as ''Lurdinha''; this nickname is due to the fact that the bride of one of the soldiers, named Maria de Lourdes, was a seamstress and the sound of MG 42 was similar to the sound of her sewing machine (''Lourdinha'' is a common nickname in Brazil for women called Maria de Lourdes).<ref>{{Cite news | url=https://www.bbc.com/portuguese/brasil-43398292 | title=O soldado que transformou em música uma batalha histórica para o Brasil na 2ª Guerra| newspaper=BBC News Brasil| date=2018-03-18| last1=Bernardo| first1=André}}</ref><ref>{{cite news |last= |first= |date= |title=A LOURDINHA ESTA CANTANDO |language=Pt|trans-title=LOURDINHA IS CANTAND |url=http://rubi.casaruibarbosa.gov.br/bitstream/20.500.11997/3875/1/Di%2bi%CC%81rio%20Carioca%20-%20DE%20-%2019441945.pdf |url-status=dead |work= |location= |archive-url=https://web.archive.org/web/20180714022120/http://rubi.casaruibarbosa.gov.br/bitstream/20.500.11997/3875/1/Di%2bi%CC%81rio%20Carioca%20-%20DE%20-%2019441945.pdf|archive-date=14 July 2018 |access-date=24 October 2024}}</ref><ref>{{Cite thesis |last=Costa |first=Marcos Antonio Tavares da |date=2009 |title=A Força Expedicionária Brasileira: Memórias de UM Conflito |url=http://www.ufjf.br/ppghistoria/files/2009/12/Marcos-Antonio-T-Costa9.pdf |archive-date=14 July 2018 |archive-url=https://web.archive.org/web/20180714193031/http://www.ufjf.br/ppghistoria/files/2009/12/Marcos-Antonio-T-Costa9.pdf |url-status=dead |type=Master's Degree in History, Culture and Power |location=Juiz de Fora, Minas Gerais, Brazil |publisher=Federal University of Juiz de Fora |access-date=13 July 2018}}</ref>

== Small arms doctrine ==
[[File:MG42 1 noBG.jpg|thumb|MG 42 with its bipod unfolded]]

The German tactical infantry doctrine of the era based a (10-man ''Gruppe'') [[squad]]'s firepower on the general-purpose machine gun in the light machine gun role.<ref>[https://ww2clash.com/small-units.php "Small Units Ground War. TO&Es of Small Units: German and Soviet Organization in 1941".]</ref> The advantage of the general-purpose machine gun concept was that it added greatly to the overall volume of fire that could be put out by a squad-sized unit.<ref>Hogg, Ian V., & Weeks, John.

Operating crews could lay down a barrage of fire, pausing only to reload or to replace the barrel, which could be done in less than 10 seconds. This allowed the MG 42 to tie up larger numbers of enemy troops than was otherwise possible. The Americans and the British trained their troops to take cover from the fire of an MG 42, and assault the position during barrel replacement.{{sfn|McNab|2012|p=33}}<ref>[https://books.google.com/books?id=K4HpAAAAMAAJ&dq=pull+belt+mg42&pg=RA2-PA24 Infantry Journal, Volumes 60-61, February 1947, page 24]</ref> The (slower) [[Rate of fire#Sustained or rapid rate|rapid firing rate]] used in emergency/final defensive line situations of the MG 42 was up to 500 rounds per minute.<ref name="MG42handbookHDV1817" />

The [[Allied nations]]' infantry doctrines of World War II based a squad's/rifle section's firepower on the rifleman and a magazine-fed light machine gun (BAR, Bren, DP-27/DPM, FM 24/29) whose [[Rate of fire#Cyclic rate|cyclic fire rates]] were typically 450 to 600 rounds per minute. The Allied nations had machine guns with similar rates of fire, but mounted them almost exclusively in aircraft, where the fleeting opportunities for firing made such high rates necessary. Weapons such as the M1919 Browning machine gun and the Vickers K machine gun, were only issued to infantry in specialized circumstances.

===Light machine gun fire support role===
[[File:Bundesarchiv Bild 101I-204-1727-18, Jugoslawien, Soldaten mit MG 42 im Schnee.jpg|thumb|Machine gun team in Yugoslavia]]

A German infantry ''Gruppe'' (squad) at the start of the war consisted of ten men; a non-commissioned officer or ''[[Unteroffizier]]'' squad leader, deputy squad leader, a three-man machine gun team (machine gunner, assistant gunner/loader and ammunition carrier) and five riflemen. As personal small arms, the squad leader was issued a [[rifle]] or, around 1941, a [[submachine gun]], the machine gunner and his assistant were issued [[pistol]]s and the deputy squad leader, ammunition carrier and the riflemen were issued rifles. The riflemen carried additional ammunition, [[hand grenade]]s, explosive charges or a machine gun tripod as required and provided security and covering fire for the machine gun team.<ref>{{cite book |last=Bull |first=Stephen |date=2004 |title=World War II Infantry Tactics: Squad and Platoon |others=Illustrated by Mike Chappell & Brian Delf |location=Osceola, WI |publisher=Osprey |pages=22–23 |isbn=9781841766621}}</ref><ref>''[https://web.archive.org/web/20120925172608/http://usacac.army.mil/cac2/cgsc/carl/wwIIspec/number09.pdf The German Squad in Combat]''. United States War Department, Military Intelligence Service, December 25, 1943.</ref> Two of the standard issue bolt-action Karabiner 98k rifles in the squad could be replaced with semi-automatic Gewehr 43 rifles and occasionally, StG 44 assault rifles could be used to re-arm the whole squad, besides the machine gun. A full ''Gruppe'' (squad) carried 1,800 rounds of ammunition for the machine gun between them.{{sfn|McNab|2012|pp=43}}

===Medium machine gun fire support role===
[[File:1657 - Salzburg - Festung Hohensalzburg - Schweres Maschinengewehr M42.JPG|thumb|right|The MG 42 mounted on the ''Lafette 42'' tripod with an added optical sight]]

In the German [[heavy machine gun]] (HMG) [[platoon]]s, each platoon served four MG 34/MG 42 machine guns, used in the sustained fire mode mounted on tripods.<ref name="AP-GerPlatoon">{{cite web|last1=Murray|first1=Dave|title=The German Infantry Platoon|url=http://www.avalanchepress.com/BehindCounters2.php|website=avalanchepress.com|publisher=Avalanche Press|access-date=18 February 2017}}</ref> In 1944, this was altered to six machine guns in three sections with two seven-man heavy machine gun squads per section as follows:

* Squad leader (NCO); [[MP 40|MP40]]
* Machine gunner (private); MG 34/MG 42 and [[Walther P38]]
* Assistant gunner (private); pistol
* Three riflemen (privates); rifles
* Horse leader for horse, cart and trailer (private); rifle

The optimum operating crew of an MG 42 in its medium machine gun role was six men: the squad leader, the machine gunner who carried and fired the gun, the assistant gunner/loader who carried the tripod, and three riflemen who carried 1,800 rounds of ammunition between them, spare barrels, entrenching tools, and other items.{{sfn|McNab|2012|pp=39}}

To enable the machine gun for its long-range [[direct fire]] and [[indirect fire]] support roles, optical sights could be added to a ''Zielfernrohrhalter'' (optical sight mounting bracket) on the [[#Lafette 42 tripod|tripod]], allowing operating crews to continue using advanced planned and unplanned firing methods developed during World War I, though [[plunging fire]] or [[indirect fire|indirect]] fire methods were not as commonly used by machine gunners during World War II as they were during World War I.<ref>{{cite web |title=How The Machine Gun Changed Combat During World War I |website=Norwich University Online |url=https://online.norwich.edu/academic-programs/resources/how-machine-gun-changed-combat-during-world-war-i}}</ref>

==Operation==

[[File:Bundesarchiv Bild 101I-582-2122-33, Frankreich, Fallschirmjäger mit Fla-MG.jpg|thumb|''Dreibein 34'' (a simple high-standing anti-aircraft tripod) mounted MG 42 in front of [[Rommel's asparagus]] against aerial invasion]]

One of the ''Einheitsmaschinengewehr'' (Universal machine gun) roles was to provide low-level anti-aircraft coverage. A high cyclic rate of fire is advantageous for use against targets that are exposed to a general-purpose machine gun for a limited time span, like aircraft or targets that minimize their exposure time by quickly moving from cover to cover. For targets that can be fired on by a general-purpose machine gun for longer periods than just a few seconds, the cyclic firing rate becomes less important. As a consequence, one of the MG 42's most notable features was its high cyclic rate of fire of about 1,200 to 1,500 rounds per minute, twice the rate of the Vickers and Browning machine guns, which fired at a rate of about 600 rounds per minute.<ref name=MG42handbookHDV1817/> The ear could not easily discern the sound of individual [[bullet|shot]]s being fired, hearing a sound described as like "ripping cloth" or a buzzsaw.

The MG 42's high cyclic rate of fire sometimes proved a liability mainly in that, while the weapon could be used to devastating effect, it could quickly exhaust its ammunition supply. For this reason, it was not uncommon for all soldiers operating near an MG 42 to carry extra ammunition, thus providing the MG 42 with a backup source when its main supply was exhausted. Another disadvantage of the MG 42 was that the high cyclic rate of fire led to the barrel overheating quickly during rapid fire. After around 150 rounds of rapid fire, the gun operator would open a side hatch (leading to the barrel) and replace the hot barrel with a new cooler one. Non-observance of this technical limitation renders the barrel prematurely unusable.<ref name=MG42handbookHDV1817/> The machine gun crew member responsible for a hot barrel change was issued protective [[asbestos]] mitts to prevent burns to the hands.

The German military instructed that sustained fire must be avoided at all costs. They ruled that the results of sustained fire were disappointing and that the expenditure of ammunition involved was "intolerable."<ref name="GermanMG42Views" /> In the bipod-mounted light machine gun role, MG 42 users were trained to fire short bursts of 3 to 7 rounds and strive to optimize their aim between bursts fired in succession.<ref name="GermanMG42Views" /> According to comparative tests by the US military under battle conditions, 5 to 7 round bursts with 22 bursts in a minute were most effective.{{sfn|McNab|2012|pp=35}} For its medium machine gun role, the MG 42 was matched to the newly developed ''Lafette 42'' tripod. In this role, MG 42 users were trained to fire short bursts and bursts of 20 to 50 rounds and strive to optimize their aim between bursts fired in succession.<ref name="GermanMG42Views" /> As a consequence of factors like the time spent reloading, aiming, changing hot barrels if necessary to allow for cooling, the MG 42's practical [[Rate of fire#Effective rate|effective rate of fire]] was 154 rounds per minute, versus 150 rounds per minute for the MG 34.<ref name="GermanMG42Views" />

==Design details==
[[File:Schnittbild.MG3.jpg|thumb|MG 42 based MG3 in 7.62×51mm NATO]]
[[File:Jagdpanzer IV Prototyp (39076253362).jpg|thumb|Jagdpanzer IV prototype with 2 opened front facing [[firing port]]s next to the main gun]]

The MG 42 is a [[7.92×57mm Mauser]], air-cooled, [[belt fed]], [[open bolt]], recoil-operated machine gun with a quick change barrel.

Its parts are attached to a {{convert|2.5|mm|in|1|abbr=on}} thick stamped sheet metal housing that functions as the receiver and barrel sleeve.

It weighed 11.57&nbsp;kg in the light machine gun role with the [[bipod]], lighter than the MG 34 and easily portable. The underfolding bipod, the same one used on the MG 34, could be mounted to the front near the muzzle to minimize shot dispersion or the center of the gun near the balance point offering more flexibility depending on how and where it was being used.

The shoulder stock is designed to permit gripping with the left hand to hold it secure against the shoulder.

The MG 42 incorporated lessons hard-won on the [[Eastern Front (World War II)|Eastern Front]]. Both the cocking handle and the catch for the top cover to the working parts were designed so that the gunner could operate them wearing arctic mittens or with a stick or rod. This was vital for winter conditions where contact by bare flesh on cold metal could cause severe injury, such as instant [[frostbite]]. The MG 42 also functioned well in other climates; dust and dirt in North Africa and Italy was less likely to jam the MG 42 than the more temperamental MG 34.

The MG 42 is capable only of [[Automatic firearm|fully automatic]] fire. Single shots are difficult, even for experienced operators, due to the weapon's high cyclic rate of fire and  the ability to fire a short burst of no more than three rounds was usually accepted as the training standard. The weapon features a [[recoil booster]] at the muzzle which adds extra rearwards force to augment that caused by [[recoil]], thereby improving functional reliability and rate of fire. Besides amplifying recoil and managing and timing rearwards force exerted by propellant gas generated pressure, the recoil booster assembly ends in a [[muzzle shroud]] and also functions as a guide sleeve for the barrel and a [[flash hider|muzzle flash arrester]].

As the barrel of the MG 42 is changed through the side of the barrel shroud, rather than directly from the rear as in the MG 34, this made the MG 42 unsuitable for use as internal secondary or co-axial armament on World War II era German tanks or other armored vehicles, with the exception of the [[Jagdpanzer IV]]. Early versions of the Jagdpanzer IV carried two standard (no modification made) MG 42s on both sides of the main gun mantlet/glacis, firing through a [[firing port]] which was protected by an armored cover plate; the MG 42s were retracted when not in use. Later version Jagdpanzer IVs carried only one MG 42 as internal secondary armament.<ref>[https://tanks-encyclopedia.com/ww2/nazi_germany/jagdpanzer-iv.php "Jagdpanzer IV".] ''Tank Encyclopedia''.</ref>

The MG 42 belt-feed mechanism inspired the design used in the [[M60 machine gun]].<ref name="Century 2000. page 379">Hogg, Ian V. & John S. Weeks (2000). Military Small Arms of the 20th Century. 7th Edition. by Krause Publications, p. 379.</ref> The trigger mechanism of the [[FN MAG]] or MAG-58 is a virtual copy of the MG 42's, and the FN MAG's belt-feed mechanism is also very similar.

===Operating mechanism===
[[Image:DCB Shooting MG42 Roller system.JPG|thumb|right|MG 42 roller-locked system]]
[[File:Kinematik, MG42 rollenübersetzter Verschluss mit kurz zurückgleitendem Lauf CC BY-SA 4.0 Autor Grasyl.png|thumb|MG 42 roller-locked boosted short recoil action diagram]]

The roller-locked bolt assembly consists of a bolt head, two rollers, a striker sleeve featuring a wedge-shaped front, bolt body, and a large multi strands around a central coil return spring, which is responsible for pushing the bolt assembly into battery (the locked position) and returning it there when it is unlocked and pushed backwards by the recoil of firing or by the charging handle. As the striker sleeve is movable back and forth within the bolt assembly, the return spring is also responsible for pushing the striker sleeve forward during locking (described below). The bolt assembly locks with the barrel's breech (the end the cartridge is loaded into) via a prong type barrel extension behind the breech. As it is recoil-operated and fired from an open bolt, the weapon must be manually charged with the side-mounted charging handle.

The roller-locked recoil operation functions as follows: two cylindrical rollers, positioned in tracks on the bolt head, are pushed outwards into matching tracks in the barrel extension by the striker sleeve and lock the bolt in place against the breech. In the locked position during firing, the rollers rest on parallel surfaces relative to the [[bore axis]] on the bolt head ensuring a full lockup. Upon firing, rearward force from the recoil of the cartridge ignition combined with the additional rearward force generated by the muzzle booster start to move the barrel and bolt assembly rearwards for a total distance of {{convert|21|mm|in|1|abbr=on}}. These two parts start the unlocking sequence after the barrel and bolt assembly have moved {{convert|7|mm|in|1|abbr=on}} rearwards when the parts have moved far back enough that the rollers start the rest on angled/oblique surfaces and allow the rollers to move inwards, controlled by the wedge-shaped front of the striker sleeve, back to their previous position, unlocking the bolt head and allowing the bolt assembly to further recoil rearwards, extracting the spent cartridge case and ejecting it downwards through an ejection port normally covered by a spring-loaded dust cover at the bottom of the receiver, just in front of the trigger group. The spring-loaded dust cover automatically opens when the gun is fired, but the user has to close it after firing to prevent dirt entering the receiver through the open port.{{sfn|McNab|2012|p=44}} Simultaneously, the barrel is pushed forward by a recuperator spring to its starting position. The three-wire braided return spring then pushes the bolt assembly forwards again, pushing a new cartridge out of the belt into the breech. The sequence repeats as long as the trigger is depressed.

The original MG 42 roller-locked action had an undesirable tendency to exhibit bolt-bounce. It was possible to unintentionally have high pressure gas moving backwards in the MG 42 towards the operator(s) when the action was not fully locked. This causes unacceptable dangerous conditions and out of battery ignitions can result in catastrophic gun failures. Enough guns were damaged and put out of action for repair or lost to warrant finding the cause and a solution. After investigation using [[high-speed photography]], the rollers in the bolt were found to "bounce" back and forth or oscillate up to {{convert|1|mm|in|2|abbr=on}} when lock up is proceeding and then they settle into full lock up. Once the problem was identified, the temporary solution was to design and manufacture extra sturdy ammunition with primers with a slightly slower ignition time which allowed the rollers to settle into lockup and issue that ammunition specifically for MG 42 use.<ref name="waffen-welt.de">{{cite web|url=http://www.waffen-welt.de/bilder/DiePatrone7.92x57.pdf|title=Die Patrone 7.92mm (8x57)|website=waffen-welt.de|access-date=8 May 2018}}</ref> A more practical solution to control the harmonics problem in the roller/wedge system and make the MG 42 less ammunition ignition timing sensitive was needed. The roller-locking system inherent problem was solved after World War II by developing and adding bolt-bounce preventing bolt catches to the action.<ref>The [[7.62×51mm NATO]] chambered [[MG 3 machine gun|MG 3]] predecessor '''MG 1A2''' (known also as the '''MG 42/59''') added new bolt-bounce preventing bolt catches to the action to resolve the ammunition ignition timing sensitivity of the preceding variants.</ref> These can also be retrofitted to MG 42 bolts.<ref>{{Cite web |url=https://www.mg-42.net/mg42_bolt_catches.htm |title=MG 42 bolt catches |access-date=8 April 2020 |archive-date=28 January 2020 |archive-url=https://web.archive.org/web/20200128004639/http://mg-42.net/mg42_bolt_catches.htm |url-status=dead }}</ref>

The cyclic firing rate of the MG 42 can be altered by installing different bolts and return springs. A heavier bolt uses more recoil energy to overcome inertia, thus slowing the cyclic rate of the machine gun. Heavy bolts also were used along with stiffer [[Hooke's law|return springs]]. The standard MG 42 bolt weight for a 1,500 rounds per minute cyclic rate of fire is {{convert|505|g|oz|2|abbr=on}}.<ref name="WG-MG42-3">{{cite web|title=MG 42 and MG 3 machine gun|url=http://modernfirearms.net/machine/de/mg-42-and-mg-3-e.html|website=World Guns|access-date=18 February 2017|date=2010-10-27}}</ref>

===Sights===
[[File:Bundesarchiv Bild 183-J14917, Sizilien, Fla - MG sichert Kolonne bei der Rast.jpg|thumb|MG 42 with auxiliary anti-aircraft "spider web" ring sight mounted]]

The open-type [[iron sight]]ing line has a relatively short {{convert|430|mm|in|1|sp=us}} radius and consists of a "∧-type" height adjustable front sight on a folding post and a leaf rear sight with an open V-notch sliding on a ramp, graduated from {{convert|200|to|2,000|m|yds|0|sp=us}} in {{convert|100|m|yds|0|sp=us}} increments.<ref name=MG42handbookHDV1817/>

An auxiliary anti-aircraft "spider web" ring sight is kept in the maintenance kit, that can be fitted on the barrel jacket to be used in conjunction with a folding anti-aircraft rear peep sight that is attached by a hinge to the rear sight element base.

An [[Night vision#Active illumination|active infrared]] device, intended primarily for night use, and consisting of a specialized mount, active {{convert|300|mm|in|1|sp=us}} infrared spotlight and accompanying infrared image converter was developed that could be used with the MG 42 and MG 34. In the later stages of World War II the bulky ''Fahr- und Zielgerät FG 1250'' (driving and aiming device [[FG 1250]]) active infrared unit was paired on  [[Sd.Kfz. 251|Sd.Kfz. 251/1 ''Falke'']] half-track armored personnel carriers to some MG 42 and MG 34 machine guns.<ref>{{Cite web|last=McCollum|first=Ian|date=23 November 2013|title=Vintage Saturday: Night Vision|url=https://www.forgottenweapons.com/vintage-saturday-night-vision/|access-date=8 August 2021|website=[[Forgotten Weapons]]}}</ref><ref>[http://www.missing-lynx.com/articles/dio/rwpanth/rwpanth_solutions.htm The Last Panther in Pomerania by Rhodes Williams IR Solutions]</ref>

===Feeding===
[[file:Method of joining metallic-link ammunition belts.jpg|thumb|left|upright|Method of joining German non-disintegrating metallic-link ammunition machine gun belts]]

The MG 42 could use [[Belt (firearms)#Non-Disintegrating Belt|non-disintegrating metallic-link belts]], which have links that wrap around the cartridge case and are linked by a coiling wire on each side. The belts are intended for multiple reuse. As in the MG 34, operation through the feed block is by a feed arm housed in the feed cover. The feeding system was based on the direct push-through of the cartridge out of the belt link into the gun's chamber. Accordingly, the link had to be of the half-open type to enable the motion of the bolt through the link. New in the MG 42 was that two belt feed pawls are linked to the front end of the feed arm by an intermediate link, in such a way that when one pawl is feeding, the other pawl is riding over the next round in the belt. Because of that, feed is performed in two steps, on both the opening and closing movement of the bolt, instead of one step as in the earlier MG 34. This enhances the smoothness of the feeding process by improved ammunition belt retention for more precise indexing with the feedway and reduces mechanical stress put on the feed unit and belt links. According to [[Infantry (magazine)|Infantry Journal]] in 1947, the operating momentum driven MG 42 feed system will not function reliably under a cyclic firing rate of 850 rounds per minute.<ref>[https://books.google.com/books?id=K4HpAAAAMAAJ&dq=pull+belt+mg42&pg=RA2-PA25 ''Infantry Journal'', Volumes 60-61, February 1947, p. 25.] ''Google Books''.</ref>

During World War II the ''Gurt 34/41''-belt family was introduced. ''Gurt 34/41'' belt links and wire spirals were made of thinner material — the ''Gurt 34'' links were made of {{convert|0.7|mm|abbr=on|3}} and ''Gurt 34/41'' links of {{convert|0.5|mm|abbr=on|3}} thick stamped steel sheet metal —  that saved ⅓ of metal and counterintuitively yielded improved performance. Belts were supplied in a fixed length of 50 rounds, but could be linked up to make longer belts for sustained firing. Ammunition boxes contained 250 rounds in five 50-round belts. A 250-round ''Patronengurt 33'' belt was also issued to machine guns installed in fixed emplacements such as bunkers. ''Patronenkasten 34'' and ''Patronenkasten 41'' [[ammunition box]]es could hold up to 300 belted rounds and were used in more static non-highly mobile situations. The ''Patronenkasten'' could contain an ''Einführstück'' belt starter-segment.<ref>[http://www.smallarmsreview.com/display.article.cfm?idarticles=1897 Feeding the Tiger By Jean-François Legendre Ammunition Belts for German MG 34 and MG 42 Machine Guns]</ref><ref>[https://www.mp44.nl/equipment/patronenkasten.htm MG 34/42 ammunition box – Patronenkasten 34]</ref><ref>[https://fjm44.com/articles/mg-3442-ammunition-box-patronenkasten-41-bdk-4/ MG 34/42 ammunition box – Patronenkasten 41]</ref>

The ''Gurttrommel'' assault drum was an alternative feed option and designed to be clipped to the left side of the gun. It was not a true magazine but held a coiled 50-round belt and corresponding ''Einführstück'' starter-segment preventing it from snagging, twisting and getting stuck during mobile assaults. The ''Gurttrommel'' belt container was commonly used until the end of World War II, with the MG 42 and the earlier MG 34.<ref>[http://www.bergflak.com/PT34.htm Patronentrommel 34 and Gurttrommel 34]</ref>

===Barrel===
[[File:Mitralieră MG 42 cu afet 26.jpg|thumb|MG 42 spare barrel unit with an opened ''Laufschützer'' container and ammunition box]]

The {{Convert|530|mm|in|1|sp=us}} long barrel and its prong type barrel extension used for lock up, made up the barrel unit of the MG 42. It could be quickly changed by the machine gun crew and weighed {{convert|1.75|kg|lb|1|abbr=on}} including the locking piece.<ref name=MG42handbookHDV1817/> The barrels could have traditional [[rifling]] or [[polygonal rifling]]. Polygonal rifling was an outgrowth of a [[cold forming|cold-hammer forging]] process developed by [[Berlin-Lübecker Maschinenfabrik#Innovation|German engineers]] before World War II. The process addressed the need to produce more durable machine gun barrels in less time than those produced with traditional methods.<ref>{{cite web|url=http://www.humanevents.com/article.php?id=37197|title=Barrels and Bullets: Conventional Versus Polygonal Rifling - Human Events|website=humanevents.com|access-date=23 December 2016|archive-date=19 February 2011|archive-url=https://web.archive.org/web/20110219155254/http://www.humanevents.com/article.php?id=37197|url-status=dead}}</ref><ref>{{cite web|url=https://gatdaily.com/hammer-forged-barrels-made-2/|title=How are Hammer Forged Barrels Made?

The different versions meant that the service life of an MG 42 barrel varied between 3,500 and 8,000 rounds assuming the barrel was used according to the regulations, which prohibited rapid fire beyond 150 rounds. Excessive overheating caused by rapid firing about 500 rounds through a barrel resulted in unacceptable wear of the bore rendering the barrel useless.<ref name=MG42handbookHDV1817/>

For carrying and protecting spare barrel units, consisting of a barrel and its locking piece, the ''Laufschützer 42'' (barrel protector) was used as a field accessory. When closed the ''Laufschützer 42'' looked like a tubular container with mountings at its ends to attached a carrying/shoulder strap. During a barrel change a cool MG 42 barrel unit coming out of the ''Laufschützer 42'' can be inserted in the machine gun and the replaced hot barrel unit can be placed in or on the opened ''Laufschützer 42'' to cool down.<ref>[https://www.germanmilitaria.com/heer/photos/H074168.html MG42 SPARE BARREL CARRIER (''Laufschützer 42'')]</ref> The ''Laufschützer 42'' was derived from the ''Laufschützer 34'' that served the same purpose for MG 34 barrel units. Later in the war the universal ''Laufschützer 43'' was introduced that could be used with MG 34 and MG 42 barrel units.<ref>[https://www.germanmilitaria.com/heer/photos/H048668.html MG34/42 SPARE BARREL CARRIER (''Laufschützer 43'')]</ref>

For the medium machine gun role a large tripod, the ''Lafette 42'', was available that included a number of features, such as recoil absorbing buffer springs, a ''Zielfernrohrhalter'' (optical sight mounting bracket) for mounting an MG Z 34 or MG Z 40 periscope-type 4× power [[telescopic sight]] containing special sighting equipment for [[indirect fire]], or the late World War II MG Z 44, designed for direct fire only.<ref>[https://www.germanmilitaria.com/heer/photos/H043382.html MG 34/MG 42 optical sight, germanmilitaria.com]</ref> Fitting such an optical sight enabled the machine gun to deliver direct fire out to {{convert|3000|m|yd|0|abbr=on}}. An accessory to lengthen these sights' periscope was available to use these sights behind cover. The ''Lafette'' could be set up in a prone, kneeling or high position. The ''Lafette 42'' weighed {{convert|20.5|kg|lb|1|abbr=on}} on its own and was a simplified version of the ''Lafette 34'' used for the MG 34, as the MG 42 could be operated more easily from a ''Lafette'' and featured no semi-automatic firing mode. The legs could be extended with a ''Lafetteaufsatzstück'' to allow it to be used in the low level anti-aircraft role, and when lowered, it could be placed to allow the gun to be fired "remotely" while it swept an arc in front of the mounting with fire. Mounted to the Lafette and aimed through the MG Z 34 or MG Z 40 telescopic sight, the effective range of the MG 42 could be extended out to {{convert|3500|m|yd|0|abbr=on}} when fired indirectly. The indirect firing method exploits the ''s.S. Patrone'' useful maximum range, that is defined by the maximum range of a small-arms projectile while still maintaining the minimum kinetic energy required to put unprotected personnel out of action, which is generally believed to be 15 kilogram-meters (147&nbsp;J / 108&nbsp;ft⋅lbf).<ref name="krtraining1">{{cite magazine |author1=Kjellgren, G.

Another unique feature of German World War II machine guns was the ''Tiefenfeuerautomat'' feature on the ''Lafette 42'' and ''Lafette 34'' tripods. It lengthened the [[Field of fire (weaponry)|beaten zone]] by walking the fire in wave-like motions up and down the range in a predefined area. The length of the beaten zone could be set on the ''Tiefenfeuerautomat''. E.g., being unsure whether the real distance was {{convert|2000|or|2300|m|yd|0|abbr=on}}, the gunner could make the mount do an automatic sweep between the elevations for {{convert|1900|to|2400|m|yd|0|abbr=on}} and back. This sweeping of a selected beaten zone continued as long as the gun fired. The ''Lafette 42'' had a ''Richt- und Überschießtafel'' (Overhead firing table) riveted to the rear body of the searchfire mechanism from the very start of production until the very end of it. In the later stages of World War II ballistic correction directions were added for overshooting friendly forces with [[7.92×57mm Mauser#German military standard ball service rifle cartridge evolution|S.m.E. - ''Spitzgeschoß mit Eisenkern'' (spitzer with iron core)]] ammunition of which the external ballistic behaviour started to significantly deviate from {{convert|1500|m|yd|0|abbr=on}} upwards compared to the ''s.S. Patrone'' (s.S. ball cartridge).<ref>{{cite web|url=http://www.bergflak.com/lafette/evo42.html|title=MG34 and MG42 Lafette wartime development part two|website=www.bergflak.com}}</ref><ref>{{cite web|url=http://www.bergflak.com/lafette/uber.html|title=The Überschießtafel|website=www.bergflak.com}}</ref> A trigger handle, which enabled the operator to fire the gun without affecting the aim, was attached to the ''Tiefenfeuerautomat'' searchfire unit.{{sfn|McNab|2012|p=50}}

There were numerous other specialist mounts for the MG 42. The ''Dreibein 34'', for example, was a simple high-standing tripod for mounting the gun in anti-aircraft mode. There were also mounts for various vehicles, motorcycle sidecars, and fortress  positions. MG 42s were mounted in multiple-gun arrangements, particularly for low level anti-aircraft defence.{{sfn|McNab|2012|pp=16–17}}

The butt-stock was produced in various wood and bakelite versions.

==Variants and developments==
[[Image:MG42-Display.jpg|thumb|right|Various configurations of MG 42, including an anti-aircraft tripod (right)]]

=== Finnish MG 42 ===
[[Finland]] acquired five MG 42s in July 1943 for evaluation. Three were tested with front units. Finland decided to produce 4,000 MG 42s modified to fire [[7.62×54mmR]] cartridges but only one modified prototype was ever made.<ref name="finland">{{cite web|title=WEAPONS FINNISH ARMY ALMOST HAD IN WORLD WAR 2, PART 1: Rifles and Machineguns|url=https://www.jaegerplatoon.net/ALMOST1.htm|date=21 August 2016|website=jaegerplatoon.net}}</ref>

=== MG 45 ===
{{Main|MG 45}}

In 1944, the material shortages in [[Nazi Germany]] led to the development of a newer version, the '''MG 45''' (or '''MG 42V'''), which had a different operating mechanism that used [[Blowback (arms)#Roller delayed|roller-delayed blowback]] as opposed to roller locking. For this reason, the MG 45 is considered a different type of firearm, as the mechanisms of these two guns are different. It used steel of lesser quality, which reduced weight to {{convert|9|kg}}, while retaining the horizontal cocking handle. First tests were undertaken in June 1944, but development dragged on and eventually only ten were built. The tested MG 45 fired 120,000 rounds in succession at a cyclic rate of fire around 1,350 to 1,800 rounds per minute.

The MG 45 had some influence in the post-war development of roller-delayed blowback system, as employed in issued [[CETME]], [[Sig Holding|SIG]] and [[Heckler & Koch]] small arms.

=== T24 machine gun ===
{{Main|T24 machine gun}}
[[File:T24mg6.jpg|thumb|T24 machine gun prototype mounted on a tripod]]

The '''T24 machine gun''' was a prototype reverse engineered copy of the German MG 42 general-purpose machine gun developed during World War II as a possible replacement for the [[M1918 Browning Automatic Rifle]] and [[M1919A4]] for infantry squads. The T24 was chambered for the [[.30-06 Springfield]] cartridge.

By February 1943, US ordnance authorities published the first report on the MG 42, following testing of a captured gun. The quick barrel changing and belt feed systems were considered some of the best design features. The US Army wanted to be able to manufacture this general-purpose gun because it was technically advanced and much easier to make than the World War II US light and medium machine guns and it was decided to convert several MG 42s to fire .30-06 Springfield M2 ball ammunition.<ref name="The M60 Machine Gun pages 12-13">The M60 Machine Gun, Kevin Dockery, pages 12–13, Retrieved 1 May 2018</ref><ref name="US T24 Machine gun MG42">[http://www.forgottenweapons.com/light-machine-guns/us-t24-machine-gun-mg42 US T24 Machine gun (MG42)] forgottenweapons.com; Retrieved 1 July 2014</ref>

Saginaw Steering Gear Division of General Motors received a contract to construct two working converted MG 42 prototypes designated as the T24 machine gun. It could also be used on an [[M2 Tripod]].<ref name="US T24 Machine gun MG42" /> The gun was made as an almost exact copy of the MG 42 which was chambered in 7.92×57mm Mauser. Some engineering changes were to use a barrel chambered for the .30-06 Springfield service round and an extremely increased weight {{convert|47|oz|0|abbr=on}} bolt and stiffer return spring in an effort to reduce the cyclic rate consistent with US rate requirements.<ref name="US T24 Machine gun MG42"/> Saginaw Steering Gear did not adjust the prototypes for the {{convert|6.35|mm|abbr=on|sigfig=2}} longer .30-06 Springfield (7.62×63mm) cartridge case.<ref>{{cite book|last1=Smith|first1=W.H.B|title=Small Arms of the World|date=1973|publisher=Stackpole|page=442|edition=10th}}</ref>

When one of the two T24 machine gun prototypes was fired at [[Aberdeen Proving Ground]], it fired only one shot and failed to eject the cartridge. A second attempt had the same result. The other prototype was plagued with excessive ejection failures and to a lesser extent failures to feed. The average cyclic rate of fire of the tested weapon was 614 rounds per minute. From January to February 1944, testing at Aberdeen Proving Ground were unsatisfactory. Firings were discontinued in February 1944 after 51 malfunctions and firing a total of 1,583 rounds by authorization of Major C. Balleisen, O.C.O.<ref name="US T24 Machine gun MG42"/><ref name="The M60 Machine Gun pages 12-13"/> In March 1944 the US military concluded that functioning of the T24 machine gun prototype was unsatisfactory and recommended that further development was required before this weapon be subjected to the lengthy and severe standard light machine gun test.<ref name="US T24 Machine gun MG42"/>

However, the realization that the .30-06 Springfield cartridge was too long for the prototype gun's mechanism to easily and reliably work with resulted in the discarding of the project.<ref name="US T24 Machine gun MG42" /> Saginaw Steering Gear did not get the opportunity to correct the flaws that caused the inability to obtain reliable uninterrupted automatic functioning and further optimize and ready the weapon for mass production before World War II ended.<ref name="The M60 Machine Gun pages 12-13" />

=== MG 51 ===
{{Main|MG 51}}
[[File:7.5mm MG 51.jpg|thumb|Swiss built W+F Bern MG 51]]

The Swiss '''MG 51''' or '''''7.5 mm Maschinengewehr 1951''''' was based on the design of the MG 42 chambered for [[7.5×55mm Swiss|7.5×55mm Swiss GP 11]]. The final design, which appeared in 1950, was in most respects still similar to the MG 42, although many components were produced by machining instead of stamping, which increased the weight, the stability and the production costs of the machine gun. To prevent short shots [[Waffenfabrik Bern]] changed the locking system from roller to [[flapper locking]]. These locking methods are similar in concept. The resulting weapon had a cyclic rate of fire of 1,000 rounds per minute, was in the light machine gun role {{convert|4.4|kg|lb|2|abbr=on}} heavier than the German MG 42, and much more finely made and finished.

=== M53 ===
[[File:M53 šarac.JPG|thumb|Yugoslavian built Zastava M53, a near exact copy of the MG 42. Note that the example in the photo is missing the trigger group.]]

In [[Yugoslavia]], this MG 42 variant was built at the state-owned [[Zastava Arms|Zavodi Crvena Zastava]] company as the '''Zastava M53''' using original German [[machinery]], retaining the 7.92×57mm Mauser chambering.<ref name="auto1">{{cite web |last=Shepherd |first=Christian |url=http://www.tactical-life.com/online/tactical-weapons/machine-gun-42/ |title=Machine Gun 42 |website=Tactical-life.com |date=2015-04-11 |access-date=2016-12-08 |archive-date=7 July 2012 |archive-url=https://web.archive.org/web/20120707064206/http://www.tactical-life.com/online/tactical-weapons/machine-gun-42/ |url-status=dead }}</ref> By doing so, the Yugoslavs retained the original weapon's design features, making the M53 a near exact copy of the German MG 42. The only major differences were a slower 950 rounds per minute cyclic rate of fire and no [[anti-aircraft]] sight mount.<ref name="g3defencemag">[https://archive.today/20120709233048/http://en.calameo.com/read/000127853fed679f5ecec G3 Defence Magazine August 2010].

=== MG 3 ===
{{Main|MG 3 machine gun}}
[[File:MG42 zu MG3 umgelabelt.jpg|thumb|Markings on an original MG 42 retrofitted to a MG 3]]

At the end of World War II the original technical drawings and data for the MG 42 were captured by the Soviets. These would eventually find their way to Czechoslovakia and Yugoslavia.<ref name="auto2">{{cite web|url=http://www.historicalfirearms.info/post/156145896479/rheinmetall-machinengewehr-3-west-germany|title=Rheinmetall Machinengewehr 3 - West Germany|website=historicalfirearms.info}}</ref> This forced Rheinmetall to reverse engineer the MG 42 for the development of the '''MG 3''' (originally the MG 1 launched in 1958), which uses the MG 42 design but was rechambered to [[7.62×51mm NATO]]. It remained a primary general-purpose machine gun of the modern German armed forces ({{Lang|de|[[Bundeswehr]]}}) <ref>{{Cite book |last=Cutshaw |first=Charles |title=Tactical Small Arms Of The 21st Century: A Complete Guide to Small Arms From Around the World |publisher=Krause Publications |year=2006 |pages=367}}</ref> until it was replaced by the [[Heckler & Koch MG5]] during the 2020s.<ref>[http://www.presseorgane.de/2019/06/mg5-ersetzt-mg3-panzergrenadierbataillo.html MG5 soll bis 2022 das betagte MG3 ersetzen, 8 June 2019 {{in lang|de}}]</ref> The MG 3 has been used by more than 40 countries around the world, and it remains in widespread service today.{{When|date=November 2023|reason=today is too vague}}

The MG 3 and its preceding variants all share a high level of parts interchangeability with the original MG 42. Like the MG 42, the MG 3 cyclic rates of fire can be altered by exchanging the standard weight (about {{convert|650|g|oz|2|abbr=on}}) bolt used for the standard 1,100–1,300 rounds per minute rate of fire for an extra weight (about {{convert|900|g|oz|2|abbr=on}}) bolt for a reduced 800–950 rounds per minute rate of fire. Those bolts also are used along with different recoil springs.<ref>{{cite web|url=http://modernfirearms.net/machine/de/mg-42-and-mg-3-e.html|title=MG 42 and MG 3 - Modern Firearms|date=27 October 2010|website=modernfirearms.net}}</ref><ref name="auto2"/>

The Italian [[:it:Beretta MG 42/59|MG 42/59]] licensed MG 3 variant produced by Beretta, Whitehead Motofides and Franchi since 1959, features an extremely heavy {{convert|1200|g|oz|2|abbr=on}} bolt which reduces the cyclic rate of fire to around 800 rounds per minute.

=== MG 74 ===
The final variant to date is the '''MG 74''', developed by Austria and since 1974 it is the standard machine gun of the [[Austrian Armed Forces]].

After its founding in 1955, the Austrian army was temporarily equipped with old guns out of U.S. stocks. Starting in 1959 these Browning M1919s were largely replaced by the MG 42 with modified barrel and bolt for the new 7.62×51mm NATO. To introduce a modern weapon of its own production the Office of Defence Technology, in cooperation with [[Steyr Mannlicher]] and [[Beretta]] developed a gun specifically for the Austrian Army. The German MG 42/59 that was introduced in 1959 with the {{lang|de|Bundeswehr}} to replace the U.S. machine guns, served as the basis, which was similar to the Austrian 7.62&nbsp;mm MG 42. Targets were to reduce, among other things, the cyclic rate of fire and weight and have more versatile sights and mount. The development of the weapon was completed in 1974. It replaced from this year the MG 42 as the MG 74 of the Austrian Federal Army.

The modifications to the basic MG 42 design include an extra heavy bolt ({{convert|950|g|oz|2|abbr=on}} vs. the {{convert|675|g|oz|2|abbr=on}} MG 3 bolt) which reduces the cyclic rate of fire to around 850 rounds per minute. The rate of fire can be varied up to cyclic rate of fire of around 1,150 rounds per minute, if necessary, by changing the bolt and return spring. In addition, a select fire trigger group was added to allow semi-automatic fire (single shot) compared to the traditional fully automatic only fire capability of the original MG 42 design. The MG 74 also has a modern polymer stock and handgrips (usually colored green) to save weight, adjustable rear sight (35° horizontal, vertical 15°) and additional anti-aircraft sight or (low light) optical sights can be mounted optional.<ref>[http://www.doppeladler.com/oebh/infanterie/mg74.htm 7,62 mm Maschinengewehr MG 74 (Steyr)]</ref>

===SIG MG710===
{{Main|SIG MG 710-3}}
[[File:SIG MG 710-3.jpg|thumb|Sig MG 710-3]]

The Swiss '''SIG MG 710-3''' general-purpose machine gun was based on the design of the MG 45 using a slight modification of the roller-delayed action and chambered for 7.62×51mm NATO. Its cyclic rate of fire is 900 rounds per minute. The first version looks very much like the MG 42.<ref name="ModernFirearms - Sig MG710">{{cite web|title=SIG MG 710 machine gun|url=http://modernfirearms.net/machine/switch/sig-mg-710-e.html|website=modernfirearms.net|access-date=26 February 2017|quote=Rate of fire 900 rounds per minute|date=2010-10-27}}</ref>

===Influence on other designs===
The MG 42's belt-feed mechanism was copied and used in the design of the M60 machine gun.<ref name="Century 2000. page 379"/> The trigger mechanism of the FN MAG or MAG-58 is a virtual copy of the MG 42's and its belt-feed is also very similar.
