The Type 85 submachine gun (85式冲锋枪, 85 Shì chōngfēngqiāng, literally means Type 85 submachine gun) is a Chinese submachine gun.
Designed to appease the dissatisfaction of troops using the Type 79 submachine gun in the People's Liberation Army, the Type 85 was designed starting from 1983 as a cheaper replacement for the Type 79. Tests were conducted on the new submachine gun design from August 20 to 30 the same year, and was approved for production and christened the Type 85 on December 27 that year.
A suppressed variant of the same submachine gun was developed around the same time, meant to replace the aging Type 64 submachine gun in service with the PLA.
Both variants of the Type 85 are currently in service with the Chinese People's Armed Police Force and special ops branches of the People's Liberation Army. However, they are expected to be replaced by the QCW-05 submachine gun in both sectors.
The Type 85, when compared to the Type 64 and Type 79 it replaced, is much simpler in construction. The Type 85 fires from an open bolt, but retains use of the blowback principle to cycle its rounds.
Most of the components of the Type 85 are made of steel, such as the tubular receiver, the folding buttstock and the integral suppressor on the suppressed variant. The weapon's shoulder stock can be folded to the right when not in use.
Similar to the Type 64, the Type 85 is select-fire; the Type 85's selector switch is located above the trigger guard on the right hand side of the weapon. The weapon feeds from 30-round magazines used by the Type 64 submachine gun.
Unlike the Type 64, however, the Type 85's rate of fire is within the accepted norm at the time, which is around 800 rounds per minute; the lower rate of fire should allow the user to have better control over the weapon during full-auto fire.
The Type 85 uses the same 7.62×25mm Tokarev Type 51 rounds as used by the Type 64 and Type 79, with the suppressed variant using the same 7.62×25mm Tokarev Type 64 rounds as the Type 64.
