It is intended for professional and amateur hunting. The carbine is simple and reliable, with an immovable barrel. Automatic reloading of the carbine is carried out by the energy of powder gases discharged from the barrel bore through the barrel opening into the underbarrel gas chamber. The barrel bore is locked with a bolt by means of locking lugs of the turning bolt. The hammer is cocked automatically by moving the frame to the rearmost position. The firing-and-trigger mechanism is mounted on the stock base plate and ensures only single-shot shooting. It can be taken to two pieces easily and quickly, without using tools, for transporting.
