The Type 05 (Chinese: 05式微声冲锋枪; pinyin: 05 Shì Wēishēng Chōngfēngqiāng; literally: Type 05 Suppressed Submachine Gun) is a Chinese submachine gun, originally designed in the late 1990s and intended to replace the Type 85 SMG.
The Type 05 submachine gun was a joint development between the PLA's 208 Research Institute and Jian She Group. This design won the Compact Submachine gun trials initiated by PLA in early 1990s, and is intended to replace earlier weapons in service with PLA, such as Type 85 silenced submachine gun. Externally resembling the new Chinese assault rifle, the QBZ-95, the Type 05 is much simpler design internally.
The Type 05 submachine gun is blowback operated weapon that fires from open bolt. The gun is made in bullpup configuration, with compact aluminium receiver and separate polymer shoulder stock/housing and pistol grip/trigger units. The Type 05 fires a 5.8x21mm DAP92-5.8 cartridge, and features a 50 round removable magazine. Its maximum effective range is 150-200m. The submachine gun is a bullpup design and has several modes of fire: 3 round burst, fully automatic and semi-automatic. Military variants are assigned a detachable suppressor.
The fire mode selector switch is located above the pistol grip, and allows for single shots, 3-round bursts and full automatic fire;charging handle is located at the top of the receiver, inside the carrying handle on Type 05 submachine guns, and on the right side on the JS9 submachine gun. Both weapons also fitted with automated grip safety. Despite the bullpup design, ejection is possible only to the right side, so firing from the left shoulder is seems to be impossible or at least dangerous for the shooter.
Type 05 submachine guns are fitted with open sights and with proprietary scope mounts at the top of carrying handle; JS submachine guns have no open sights and fitted with Picatinny rail at the top of the receiver which can accept various types of sighting equipment. Either weapon can be equipped with detachable optional silencer. Military issue Type 05 submachine guns are fed from proprietary four-row box magazines that hold 50 rounds of 5.8mm ammunition; JS submachine guns use two-row 30-round box magazines compatible with the Heckler & Koch MP5.
- QCW-05 - (Chinese: 轻武器-冲锋—微声 2005; pinyin: Qīngwuqi Chōngfēng Wēishēng; literally: Light weapon, assault, suppressed, 2005) Original variant. The QCW-05 is chambered for both the armor-piercing DAP92 cartridge and the subsonic DCV05 cartridge (both 5.8x21mm), and is suppressed. The designation QCQ-05 is given to unsuppressed QCW-05s. The QCW-05 has been issued to Chinese security forces, including the Ministry of Public Security, the People's Liberation Army, and special forces units.
- JS9mm - Export variant, designed in 2004. The JS9mm is chambered in 9x19mm and is equipped with picatinny rails to mount scopes and laser sights, but is internally similar to the QCW-05. It is offered with a detachable suppressor. The JS9mm is currently in use by some Chinese security forces. The name is a generic provisional name used by public sources to describe the weapon (Jian She 9mm submachine gun), as the weapon's official designation wasn't revealed when the weapon was first revealed, and came to be the most common name for the weapon. It is now marketed as the CS/LS2, and has been improved with ambidextrous cocking.
