The Gepard (Cyrillic: Гепард, Cheetah) is a Russian submachine gun developed by the military unit 33491 and JSC REX,[1] first designed in 1995 and presented in Moscow in 1997.
[4] Developed from the AKS-74U, the Gepard has a 65% parts commonality; it can use the .380 ACP, 9×18mm Makarov, 9×19mm Parabellum, 9×19mm 7N21, 9×21mm and 9×21mm Gyurza without a change and can use the 9×30mm Grom cartridge with a chamber replacement.
The gun can use different mechanisms of action: The receiver is shorter compared to other Kalashnikov platforms, so a special counter-balancing system can be used.
The double-stack magazine presses the rounds against the front wall.
[5][6] Unusual for Kalashnikov rifles, the magazine is placed inside the grip similar to the ST Kinetics CPW and the grip is made from polymer.
