The assault rifle was designed to fit into dimensions of a submachine gun; in doing this, much attention was paid also to production/cost parameters of the weapon to make its manufacture streamlined and economical, which ensured its popularity with consumers. The cheaper 9×39 type PAB-9 cartridge was designed at that time too.
The weapon has a gas-operated mechanism with a long-stroke gas piston, its gas chamber is elongated in the forward direction to obtain the required piston rod length. The breech is locked by a rotating bolt featuring four locking lugs. The hammer-type firing mechanism enables semi-automatic (single-shot) and full-automatic (burst) firing.

Lebedev developed the OTs-11 Tiss shortened assault rifle (length with folded stock – 490 mm. weight w/o rounds – 2.5 kg) for the same 9×39 rounds.
