MP5 A3 "H" recoil buffer

Recoil buffers are an easy and inexpensive way to eliminate damage of critical components by preventing the metal to metal contact of the slide or breech block with the frame. Made from a high density polyurethane formulated for maximum shock-absorbing characteristics, the recoil buffer is a drop-in part.
