CONSTRUCTION

The stock body is made of aluminum, machined from a solid block, with designated seating for the telescopic mechanism and for the standard stock attachment on PK/PKM. The base of the guides is steel, machined from a solid block, featuring operational holes for the telescopic mechanism.

A long rectangular button is located on the body, which, when pressed, adjusts the stock. To instantly deploy the stock, simply grab the stock by the butt and quickly pull it back. In this case, there is no need to press the button.

The telescopic frame is used to adjust the stock length within a range of up to 125 mm. The frame consists of two steel rods with a diameter of 10 millimeters, shaped with positional grooves for length adjustment.

The shoulder pad (buttstock) is made of polyurethane, produced by molding, and is installed on the butt base to soften the recoil effect.

The cheekpiece consists of a cheek (polyacetal) and a guide (aluminum) with positional grooves for height adjustment.
