Precision Machined Replacement Fits A Variety Of AK Models
Replacement for factory original piston is adjustable to fit a wide variety of Kalashnikov-family rifles, including the standard AK-47, AK-74, Tantal, and Saiga rifles. A screw-on bushing allows the installer to change the length of the threaded portion to fit different rifles. Machined from exceptionally hard, 300 Series stainless steel to exact tolerances for superior strength and optimal cycling performance. Concave cup with larger surface area than factory piston allows more positive engagement with expanding gas for greater reliability. Additional cleaning grooves reduce danger of jamming due to carbon fouling. Made in the U.S.A. to keep your gun in compliance with the U.S. Code Title 18 Section 922(r) part-source requirements.
