FM Products Mike-9 RMB Heavy Buffer

FM Products Mike-9 RMB Heavy Buffer is a recoil mitigating buffer system designed for pistol caliber carbines (PCCs). It is designed to be used with FM Products VFM-9 Upper Receiver in a short-stroke configuration. If building a PCC upper that is not short-stroke, you would need an A5 Buffer Tube to ensure bolt lock back. The RMB features a tuned reciprocating mass, a sliding buffer body, a dampening spring, and a urethane impact modifier to deliver a soft, controlled recoil impulse and to eliminate bolt bounce.
