Brownells AR-15 H3 Carbine Buffer Features The Brownells AR-15 H3 Carbine Buffer weighs in at 5.4 ounces making it the heaviest option in Brownells standard buffer lineup and a common choice for short barreled AR-15 rifles or guns that cycle too aggressively. Adding buffer mass slows bolt carrier velocity which reduces felt recoil and battering on the rifle s internals over time. This extra weight is especially useful on carbines with pistol length or short gas systems where the bolt carrier group can otherwise cycle harder than intended. Selecting the correct buffer weight for your specific gas system is one of the simplest ways to improve reliability and shooter comfort. Finished in gray this buffer is built to precise tolerances so it drops into any standard mil-spec AR-15 buffer tube without modification. It ships individually making it a practical spare part or an easy way to complete a custom parts build. Whether replacing a worn factory buffer or fine tuning a new build s recoil impulse this buffer is a straightforward upgrade path. The Brownells AR-15 H3 Carbine Buffer gives AR-15 owners a reliable way to dial in smoother more controlled function.
