QCW-05

The QCW-05 (Chinese: 轻武器-冲锋-微声-05; pinyin: Qīng wǔqì Chōngfēng Wēishēng 05; lit. 'Light weapon', 'Assault/Sub-machine gun', 'Suppressed 05', also referred to as the Type 05 Suppressed Submachine Gun) 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.

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 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 caliber.

The QCW-05 is a 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.

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 (0) and an ejection port on the right side of the weapon.
