This expert analysis from Regular Guy Training LLC details the impressive wear characteristics and endurance of the BRN-4 firearm. Through extensive testing, including 21,000 rounds with 6,000 suppressed, the BRN-4 demonstrates remarkably even wear on its moving components, particularly the front-located piston and gas rings. The system maintains reliability and a flat shooting impulse even under extreme conditions, drawing comparisons to the mechanical feel of an AK platform.
