The Battle Arms Development H2 carbine buffer (Battle Arms Development part no. AR15-BUFFER-H2) weighs 4.65 oz, a step up from a standard carbine buffer thanks to one internal steel weight paired with two tungsten weights. Mass-produced AR-15 carbines often run a little too light on bolt carrier speed for their gas system, and the added mass of an H2 buffer is one of the most common, most effective fixes for excess recoil impulse and wear on the receiver extension. It’s built for AR-15s running a collapsible stock and a standard mil-spec carbine buffer tube, dropping in as a direct upgrade over a factory buffer. Battle Arms Development is known for AR-15 components built to tighter tolerances than typical mil-spec parts.
