M2 ARMAMENT GROUP HEAVY H3 SLIDING CARBINE RECOIL BUFFER – ANTI-BOLT BOUNCE DEAD BLOWColt-Inspired Heavy Design Modernized for Forced Reset Applications | Prevents Light Primer Strikes & Bolt Bounce | Two-Piece Sliding Dead-Blow Design | Made in the USA

Eliminate cycling frustration and lock in flawless active reset timing with the M2 Armament Group Heavy H3 Sliding Carbine Recoil Buffer. Based on the time-tested full-auto sliding buffer design originally pioneered by Colt for heavy-use military platforms, this architecture has been modern-engineered and radically improved to meet the extreme demands of today’s booming Forced Reset Device (FRD) market. By utilizing a heavy-duty two-piece sliding dead-blow design, it actively counteracts forward kinetic energy to eliminate destructive bolt bounce—the single leading cause of light primer strikes, out-of-battery stutters, and dead-trigger malfunctions in high-speed setups.

Measuring the standard 3.25 carbine length, this U.S.-made heavy recoil buffer acts as an internal dead-blow hammer. Upon forward battery closure, the solid rear section strikes the bolt carrier group a fraction of a second after initial impact, killing carrier rebound and driving the bolt home with authority. This mechanical dampening provides the exact mass and momentum needed to tame excessive carrier velocity across everything from short 7″ PDW barrels to full-length carbines.
