I just really like the design. Simple and functional. It looks like it should fire something more powerful than the 7.62x25mm Tokarev.
The Type 79 submachine gun is more or less patterned after the Type 56 (AK-47) assault rifle. It uses gas-operated, rotary bolt action with short stroke gas piston located above barrel. The bolt group and fire mode/safety switch are similar to those of the Type 56 rifle. The barrel, receiver, pistol grip, magazine and shoulder stock are all made from stamped steel. The weapon fires 7.62 X 25mm pistol cartridge in either single or fully automatic mode. Ammunitions are fed from a straight box magazine that holds 20 rounds. Shoulder stock folds up and forward when not in use.
