The QCW-05 (Chinese: 微声冲锋枪, 2005; pinyin: Wēishēng Chōngfēng Qiāng, 2005; literally: "Suppressed Assault Gun, 2005") (officially translated in pinyin as Qiāng Chōngfēng Wēishēng, literally 'Gun, Assault, Suppressed') (also referred to as the Type 05) is a 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 for the People's Liberation Army Ground Force, the People's Liberation Army Special Operations Forces and the People's Armed Police. This weapon is designed for the 5.8×21mm DCV05 sub-sonic round that is also used by the QSW-06 Silenced Pistol.

On 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 and the Type 85 silenced submachine guns, beating out other competitors such as the 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. 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 calibre. The QCW-05 is intended to be PLA's frontline personal defence weapon for personnel in non-combat roles such as vehicle crews and aircrews who would normally be confined to quarters where a full assault rifle would be unwieldy and by specialised operation units such as the People's Liberation Army Special Operations Forces and People's Armed Police.
