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.

[citation needed] The QCW-05 is a blowback, open bolt bullpup silenced submachine gun that is capable of either full automatic or semi-automatic fire.

It 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.

[4] The use of the 5.8×21mm DV05 subsonic round reduced the QCW-05's muzzle velocity to approximately 150 m/s (490 ft/s) and gives the submachine gun an effective range of 50 m (160 ft) 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.
