Built to perfect the design of PM2 V1 Submachine gun. PM2 V2 still uses 9 x 19 mm parabellum ammunition with blowback operating mechanism and also has adjustable rear sight. The perfected SMG can use an integrated silencer which can be attached on the gun’s muzzle. The silencer is able to significantly reduce loud firing sound. This SMG also comes with folding stock, which can reduce the overall length to increase mobility.
