K-50

The K-50 is a development name of the unsuccessful competitor of Vympel R-33 AA missile.

The K-50m is a submachine gun developed by the North Vietnamese military and manufactured in North Vietnam during the Vietnam War.

Design details
The K-50m was a variant of the Soviet PPSh-41. Magazine-fed from a 35-round box magazine, the chief difference was that the cooling sleeve of the K-50 was truncated to three inches and a foresight based on that of the French MAT-49 was attached to the front of the barrel. The gun's skeleton stock was also identical to that of the MAT-49.

The K-50m was manufactured in the 7.62x25mm Tokarev cartridge.
