Type 85 submachine gun

The Type 85 () is a Chinese submachine gun, developed during the early 1980s as a less expensive replacement for the Type 79 submachine gun. The weapon's silenced version was also developed to replace the Type 64 submachine guns in service with the People's Liberation Army (PLA).
History.
Design of the Type 85 started between 1979 and 1983 and it was classified in 1985. Design work was done by the 208th Research Institute of China Ordnance Industry. Throughout the Type 85's development, there was criticism of its appearance as it looked like a toy gun at first glance. The Type 85 was eventually adopted to start replacing the Type 64 in PLA service.
The development of the Type 85 was planned to eventually replace the Type 79 in PLA service.
Design.
In January 1980, two prototypes were made for firearms testing. In 1981, trials were conducted with the weapons being tested in combat trails with single and full auto modes used. Initial feedback suggests that while handling was good, there are improvements that could be made. One of the problems encountered in trials was with trigger sensitivity.
The Type 85 submachine gun is a simple blowback weapon that fires from an open bolt. The weapon's mechanism was partially based on the Type 64. Parts made for the regular and supprssed version are interchangeable, except for the barrels.
The safety and fire mode selector lever is located at the right side of the trigger unit, above the trigger guard. The Type 85 allows for single shots and full automatic fire, which is indicated in the receiver 0, 1 and 2.
The weapon is optimized for special 7.62×25mm (Type 64) ammunition with heavy, subs+onic bullets, but can also fire standard 7.62mm Type 51/7.62×25mm TT ammunition (with increased loudness). There was a 5.8mm version being researched for potential adoption, but it was never adopted into service.
The Type 85 SMG is fed using the same 30-round box magazines as the Type 64 SMG. There is also a steel shoulder stock, which folds to the right side.
