Kaw Valley Precision H3 Carbine Buffer 5.4 oz AR-15

A heavier buffer slows the bolt carrier down, and that single change fixes a lot of AR-15 problems. The KVP H3 weighs 5.4 ounces against the 3 ounces of a standard carbine buffer, which is the usual prescription for an overgassed carbine, a suppressed gun, or a big bore build that beats itself up.

What you get is less bolt bounce, brass that lands in a pile instead of the next county, softer felt recoil, and less wear on the receiver extension and the rear of the carrier. Two brass weights ride inside a stainless steel carbine body, so it drops into any mil-spec carbine receiver extension with nothing else to change. If your gun is running hot and violent, start here before you touch the gas block.
