The '''Colt 9mm SMG''', also known as the ''' Colt Model 635''' or ''' Colt M635''', is a [[9×19mm Parabellum]] [[submachine gun]] manufactured by [[Colt's Manufacturing Company|Colt]], based on the [[M16 rifle]].<ref name="coltsmg0">{{cite web|url=http://www.colt.com/mil/SMG.asp |title=Colt Weapon Systems |date=2003-05-18 |access-date=2016-11-07 |url-status=bot: unknown |archive-url=https://web.archive.org/web/20030518122948/http://www.colt.com/mil/SMG.asp |archive-date=2003-05-18 }}</ref>

==Design details==
The Colt 9mm SMG is a closed bolt, [[blowback (arms)|blowback]] operated SMG, rather than the conventional [[direct impingement]] [[gas-operated reloading|gas operation]] of the standard 5.56×45mm M16 type rifle.<ref name="Tarr2013">{{cite book|last=Tarr|first=James|title=Standard Catalog of Colt Firearms|url=https://books.google.com/books?id=CaxuAAAAQBAJ&pg=PA237|access-date=31 August 2016|year=2013|publisher=Krause Publications|location=Iola, Wisconsin|isbn=978-1-4402-3747-8|page=237}}{{Dead link|date=December 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> As a [[closed bolt]] weapon, the Colt SMG is inherently more accurate than [[open bolt]] weapons such as the Israeli [[UZI]].<ref>Technical Memorandum 2-79. AIMING POINT DISPLACEMENT FROM FIRING A RIFLE FROM THE OPEN-BOLT POSITION.

The overall aesthetics are identical to most M16 type rifles. Changes include a large plastic brass deflector protruding from the rear quarter of the ejection port, and a correspondingly shorter dust cover. Factory Colt 9mm SMGs are equipped with a 10.5&nbsp;inch length barrel and have an [[M16 rifle|M16]] style upper receiver, which means they feature a fixed carry handle, no forward assist and A1 sights (with 50 and 100 meter settings). The magazine well of the receiver is modified with pinned-in blocks to allow the use of smaller 9 mm magazines. The magazines themselves are a copy of the UZI magazine, modified to fit the Colt and lock the bolt back after the last shot.<ref name="Thompson2016">{{cite book|last=Thompson|first=Leroy|title=The M3 "Grease Gun"|url=https://books.google.com/books?id=uLP1CwAAQBAJ&pg=PT141|date=19 May 2016|publisher=Bloomsbury Publishing|isbn=978-1-4728-1109-7|pages=141–142}}</ref>

==Variants==
{{details|topic=Colt 9mm SMG variants|AR-15 variants}}
Current Colt production models are the R0635 (RO635) which features a Safe/Semi/Full Auto [[selective fire]] trigger group and the R0639 (RO639) which features a Safe/Semi/3-round Burst selective fire trigger group.

The 633 was a modified compact version with a {{convert|7|in|mm}} barrel, hydraulic buffer and simplified front sight post used by the DEA and the Department of Energy.<ref name="Peterson2011">{{cite book|last=Peterson|first=Philip|title=Standard Catalog of Military Firearms: The Collector's Price and Reference Guide|url=https://books.google.com/books?id=aftMDn2bd14C&pg=PA387|date=2011|publisher=F+W Media|location=Iola, Wisconsin|isbn=978-1-4402-2881-0|page=387}}{{Dead link|date=December 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name="DEA">{{cite book|last=Sweeney|first=Patrick|title=Gun Digest Book of Suppressors|url=https://books.google.com/books?id=5m4kCwAAQBAJ&pg=PA45|date=18 January 2016|publisher=F+W Media, Inc.|location=Iola, Wisconsin|isbn=978-1-4402-4532-9|page=45}}{{Dead link|date=December 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

The most common model is the 635, the latest version of which are simply marked SMG 9mm NATO.<ref name="Lewis2011">{{cite book|last=Lewis|first=Jack|title=Assault Weapons|chapter-url=https://books.google.com/books?id=s2AbzqChZBYC&pg=PA210|year=2011|publisher=Gun Digest Books|location=Iola, Wisconsin|isbn=978-1-4402-2400-3|pages=208–210|chapter=A Case of Colt Confusion}}{{Dead link|date=December 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Until early 2010s, there are newer variants, R0991(RO991), R0992(RO992) and R6951 are introduced. The R0991 features Safe/Semi/Full Auto selective fire is constructed with [[Rail Integration System|Rail Integration System (RIS)]] [[Picatinny rail|picatinny rails]] on the flat-top receiver as well as around the barrel which allows the easy mounting of ancillary devices, has 10.5" barrel and equipped with a third generation composite buttstock; The R0992 has almost all the same features to the R0991, except the selective fire mode is Safe/Semi/3-round Burst only; The R6951 has almost all the same features of the R0991 and R0992, but doesn't have selective fire and has a 16.1" barrel instead of the 10.5" one.

A suppressed variant known as the "DEA model" exists that uses an integral Knights Armament Company made suppressor covered with an M16A2 handguard.<ref name="CSMGV">{{cite web | url=https://gunmagwarehouse.com/blog/the-colt-smg-and-its-many-clones/ | title=The Colt SMG and Its Many Clones | date=5 April 2023 }}</ref>
