Compatibility Notice:

          The parts listed on our website are NOS (New Old Stock) originally manufactured by Poly Technologies, Inc. of China between 1986 and 1989. These were produced at State Arsenals 416 and 386 during that time and some parts should be compatible with later production MAK-90 rifles produced by China North Industries Corporation (NORINCO). We, however, only guarantee the proper fit and function of these parts on rifles imported by Keng's Firearms Specialty, Inc. between 1985 and 1989. Please note that PRC Type 56-pattern parts are not compatible with Russian, Hungarian, Romanian or Bulgarian-manufactured AK-pattern rifles, so these parts should not be used on rifles produced in those countries or on tooling imported from those countries.
