The Vityaz-SN is a 9x19mm Parabellum submachine gun developed in the early 1990s by Izhmash. It is based on the AK-74 rifle platform and offers a high degree of parts commonality with the AK-74[1] It is the standard submachine gun for all branches of Russian military and police forces[2]

Design details

The Vityaz-SN is a lightweight selective fire weapon that uses a simple closed bolt, straight blowback method of operation. As such, it has no gas system and the internal components have been modified accordingly. The bolt carrier with integral charging handle is similar to AK, however the piston rod and rotary bolt were removed and the piston extension was plugged with a steel insert. The return spring and guide rod are identical to those of the AK.

The Vityaz has a four-groove barrel with a 240 mm (1:9 in) right-hand rifling pitch. It is chambered for the 9x19mm Parabellum pistol cartridge and will also fire the new high-pressure armor-piercing 57-N-181SM round that can penetrate soft body armor. The gun is fed from a 30 round box magazine and comes with fastening device that joins two magazines together.[3] Its muzzle brake has a three small rectangular port on each side that serves to reduce muzzle rise, however the main purpose of this device is to protect the muzzle from damage. It can also be equipped with a detachable sound suppressor.[4]

The Vityaz shares the same trigger and safety mechanisms of the AK-74 rifle. The selector lever is placed on the right side of the receiver, above the trigger, and has three settings: the uppermost "safe" setting disables the trigger and physically blocks the charging handle; the middle position (marked "АВ") enables fully automatic fire and the lowest position ("ОД") will activate the semi-automatic function of the trigger. It also utilizes the AKS-74 shoulder stock, which folds to the left side of the receiver like the AK-74. The pistol grip is identical to the grip on the AK-100 series and is made of a black fiberglass-reinforced polyamide. The forearm has attachment points for laser target designator, tactical flashlight and fore grip.[5]

The Vityaz-SN is provided with two types of mounting rails for optical or collimator sights. A Picatinny rail on top of the receiver or a dove-tail side rail. It also has a standard AK-type front and rear sights.[6]
