The Wraithworks Heavy Reciprocating Buffer (brand part number HS3B) swaps into an AR-platform buffer tube in place of a standard carbine buffer, adding real mass to the reciprocating parts. At 7.7 ounces, it’s substantially heavier than a typical carbine buffer, which slows the bolt carrier’s cyclic rate and helps calm felt recoil and bolt bounce on a hard-recoiling or over-gassed build. It’s a simple, direct swap for anyone tuning an AR’s recoil impulse without changing the gas system.
