Parabellum Armament Ratchet Charging System for Standard AK type Rifles

Parabellum Armament Ratchet Charging System for Standard AK type Rifles. The Ratchet Charging System, or “RCS” is a revolutionary development for the AK-47/74 Series Rifle. The RCS is a simple, drop-in, gas tube replacement system that provides the operator with a left side, non-reciprocating, folding, charging handle. RCS also features a true bolt “hold open” that is found on various modern rifles such as the H&K family of weapons.
