Bcm Stock Mod 0 Fde – Fits Ar-15 Mil-spec

The WILSON SHOK-BUFF prevents the slide from battering the frame during recoil by sandwiching a 1/10 thick poly fiber buffer between the slide and frame contact areas. We feel the original SHOK-BUFF is the optimum balance between shock absorption and longevity. Easily replaceable after absorbing up to 1000 rounds of repeated firings. Fits: All except C & D
