AR Buffer System

The AR buffer system is one of those components that doesn’t get enough credit until something goes wrong. Get the wrong buffer weight for your gas system and caliber, and you’re dealing with short-stroking, bolt bounce, failures to feed, or a rifle that batters itself to death one round at a time. Get it right, and your AR runs smooth, cycles reliably, and stays on target. That’s why having access to the right parts — heavy buffers, carbine buffers, rifle-length buffer tubes, buffer springs, spacer weights, and complete buffer assemblies — actually matters.

Components here come from brands like Aero Precision, Rise Armament, Faxon, Midwest Industries, and Rubber City Armory — makers that AR builders and gunsmiths actually trust when reliability isn’t optional. Whether you’re dialing in a pistol-caliber build, tuning a mid-length gas system, or swapping out a milspec tube for a billet upgrade, the right part is here and ready to ship.
