Return mechanism bolt includes two springs, it provides smooth operation automation.

    firing mechanism - a hammer type, with the same shape of the mainspring, like the AK-47. USM is in a separate building, which reduces the load on him while shooting. An original feature is the use of the hammer as a disconnector sear with the trigger.

    On the barrel is attached a cylindrical slotted flash suppressor. It has five longitudinal slots arranged and profiled so that the arrestor also plays a role compensator. Moreover, it masks the shot when shooting at night and protects the trunk from pollution.

    safety lever dual action: it simultaneously locks the trigger and restricts the movement of the bolt back, closing notch receiver. Descent provides production shot only when fully latched gate.

    Forearm, consisting of two halves, equipped with a large number of longitudinal slots for cooling, the stock frame with an integrated pistol grip originally made from molded plywood. In the 1990s, plywood replaced glass fiber reinforced polyamide.
