Mission

Combat and maintenance characteristics of the SR-2 sub-machine gun meet requirements of the Personal Defence Weapon programme. It is capable of killing personnel wearing body armour at a range of up to 200m, as well as destroying unarmoured vehicles at a range of up to 100 m. SR-2 fires several types of 9x21mm rounds, including the SP-10 enhanced penetration round, and SP-11 round with a lead core. Penetration capability of bullets is 2.5-5 times higher than that of 9x19mm Para.

Small dimensions of SR-2, together with the original armpit holster ensure comfortable and covert carrying of gun and short combat readiness time.

SR-2 is gas-operated with blocking of the barrel by rotation of the breech. A trigger mechanism is of a striker type, providing for single-shot and full-automatic fire. A flag-type safety catch is on the right side of the barrel chamber, while a selector lever is on the left side. Reloading handle is folded when on the move for convenient carrying.

A sight consists of a backsight and a twoposition foresight, designed for effective aiming at 100 and 200 m. A top-of-barrel chamber features a bracket for mounting a collimator sight.

The sub-machine gun is fed from a 20- or 30-round two-row inserted magazine. A folding metal butt is in one line with the barrel axis when firing to decrease flipping of the barrel. It is folded upwards when on the move and fixed.

The sub-machine gun is in the inventory of the Russian Armed Forces.
