The '''QCW-05''' ({{zh|p=Qīng wǔqì Chōngfēng Wēishēng 05|l=Light weapon, Assault/Sub-machine gun, Suppressed 05|c=轻武器-冲锋-微声-05}}, also referred to as the Type 05 Suppressed Submachine Gun) is a [[suppressor|suppressed]] [[bullpup]] [[submachine gun]], manufactured and developed by the [[People's Liberation Army]] (PLA) 208 Research Institute and Jianshe Industries (Group) Corporation of [[Chongqing]] under the [[China South Industries Group]]. 

==Development==
In October 2001 the Jianshe Industries (Group) Corporation (owned by the [[China South Industries Group]]) won a bid to produce the PLA's next generation of submachine gun to replace the [[Type 79 submachine gun|Type 79]] and the [[Type 85 submachine gun|Type 85]] silenced submachine guns, beating out other competitors such as the [[CF-05|Changfeng CF-05]] due to its ease of construction and operation. 

At the 2005 International Police Equipment Expo in Beijing, Jianshe revealed their final product, a [[bullpup]], blowback, open bolt submachine gun that externally resembled the [[QBZ-95]] [[assault rifle]] which was then given the designation QCW-05.<ref name="Sinodefence">{{cite web | url=http://www.sinodefence.com/army/small_arms/qcw05.asp | title=QCW05 5.8mm Silenced Submachine Gun | publisher=Sinodefence.com | date=2007-02-09 | access-date=2007-08-21 |archive-url = https://web.archive.org/web/20070819200339/http://www.sinodefence.com/army/small_arms/qcw05.asp <!-- Bot retrieved archive --> |archive-date = 2007-08-19}}</ref> 

At the 2006 MILIPOL Expo, a smaller police and export version of the QCW-05 called the 'Jianshe JS 9mm', a silenced submachine gun, was revealed to the public. The 'JS 9mm' is chambered for the popular [[9×19mm Parabellum]] caliber. 

==Design==
[[File:Evers QCW-05 mag.svg|right|100px|thumb|Outline of QCW-05s four column, fifty round, proprietary magazine]]
The QCW-05 is a [[Blowback (firearms)|blowback]], [[open bolt]] bullpup silenced submachine gun that is capable of either full automatic or semi-automatic fire. 

The QCW-05s light weight can be attributed to its small aluminum receiver and polymer construction which also lends itself well towards quicker mass-production. 

=== Operation ===
The QCW-05 has a low rate of fire in order to maintain controllability, a feature stressed from the beginning by the PLA for a weapon as light as a submachine gun. 

There is a thumb fire mode selector on the left side of the weapon directly above the grip with a semi-automatic position (1), full automatic (2), and [[Safety (firearms)|safety]] (0) and an ejection port on the right side of the weapon. 

A removable metal screw-on cylindrical suppressor is attached to the barrel of the gun.<ref name="Kaifeng Public Security Department">{{cite web | url=http://www.kfpolice.gov.cn/2006-9/2006924121445.htm | title=国产最新型QCW05式微声冲锋枪(组图) | publisher=Kaifeng Public Security Department | language=zh | date=2006-09-24 | access-date=2007-08-18 | url-status=dead | archive-url=https://web.archive.org/web/20071214114834/http://www.kfpolice.gov.cn/2006-9/2006924121445.htm | archive-date=2007-12-14 }}</ref> 

The carrying handle, which is located above the compact aluminum receiver, houses the charging handle.<ref name="Modern Firearms">{{cite web| url=http://world.guns.ru/smg/smg75-e.htm| title=Type 05 5.8mm / JS 9mm submachine gun (PR China)| access-date=2007-08-21| url-status=dead| archive-url=https://web.archive.org/web/20070822215721/http://world.guns.ru/smg/smg75-e.htm| archive-date=2007-08-22}}</ref> 

The QCW-05 shares the common trait of other bullpup weapons of being suboptimal to fire from the left shoulder given the placement of the ejection port and its proximity to the operator's face when firing.{{Citation needed|date=July 2021}}

=== Ammunition ===
{{Main|5.8×21mm}}
This weapon is designed for the [[5.8×21mm DAP92|5.8×21mm DCV05]]<ref name="Sina.com">{{cite web |date=2006-08-30 |title=国产最新型QCW05式微声冲锋枪性能结构详解 |url=http://jczs.news.sina.com.cn/p/2006-08-30/0722393854.html |access-date=2007-08-18 |publisher=Sina.com |language=zh}}</ref> sub-sonic round that is also used by [[QSZ-92|QSZ-92-5.8]], [[QSZ-11]] and [[QSW-06]] pistol.

The use of the 5.8×21mm DV05 subsonic round reduced the QCW-05's muzzle velocity to approximately {{convert|150|m/s|ft/s|abbr=on}} and gives the submachine gun an effective range of {{convert|50|m|ft|abbr=on}} which is considered adequate for a silenced weapon. 

Ammunition is fed from a detachable curved fifty round, four column, double stacked box (another initial requirement of the PLA) at the rear of the submachine gun.{{Citation needed|date=July 2021}}

=== Accessories ===
As the QCW-05 is designed for general military use rather than being used only in a specialized niche role, a suppressor can be a hindrance when a situation calls for an emphasis on the performance or size of the weapon rather than its noise reduction capabilities, which is why the suppressor is removable, or in the case of the QCQ-05 variant, completely absent.<ref name="Sinodefence" /> 

Once the suppressor is removed, the QCW-05 is essentially the same as the QCQ-05 and can fire the DAP92 round as well. 

==Variants==
[[File:QCQ05.jpg|thumb|The QCW-05 with a suppressor]]
There are two variants of the QCW-05; the JS 9mm and the QCQ-05.

===JS 9mm===
{{Main|JS 9 mm}}

A slightly smaller, somewhat externally different version of the QCW-05 designed for use by police and for export overseas. 

The JS 9mm is chambered for the [[9×19mm Parabellum]] cartridge, and it also uses the same 30 round [[Magazine (firearms)|magazines]] used by the popular [[Heckler & Koch MP5]] submachine gun. 

Another noticeable difference is that JS 9mm doesn't have a carrying handle, instead a [[picatinny rail]] could be mounted on the top.

===QCQ-05===
The QCQ-05 ({{zh|c=轻型冲锋枪, 2005|p=Qīngxíng Chōngfēng Qiāng, 2005|l=Light Assault Gun, 2005}}) (officially translated in pinyin as ''Qiāng Chōngfēng Qīngxíng'', literally 'Gun, Assault, Light') is a variant of the QCW-05 without the suppressor. 

The QCQ-05 is capable of using either the 5.8×21mm DCV05 subsonic pistol cartridge or the 5.8×21mm DAP92 pistol cartridge which is also used by the [[QSZ-92]] pistol.<ref name="Armsky.com">{{cite web | url=http://www.armsky.com/Article/yjzx/qingbingqi/Class89/200608/5655.html | title=国产最新型QCW05式微声冲锋枪性能结构详解 | publisher=Armsky.com | language = zh | date=2006-08-30 | access-date=2007-08-21 |archive-url = https://web.archive.org/web/20070317182944/http://www.armsky.com/Article/yjzx/qingbingqi/Class89/200608/5655.html <!-- Bot retrieved archive --> |archive-date = 2007-03-17}}</ref>
