Mil-Spec Carbine Buffer - 3.0oz

Ensure smooth cycling, proper bolt speed, and optimal recoil management with the Mil-Spec Carbine Buffer. Designed as a direct drop-in replacement for standard AR-15 carbine buffer systems, this 3.0 oz recoil buffer provides the exact weight and length required for reliable feeding, lockup, and ejection across standard calibers like 5.56 NATO, .223 Remington, and .300 Blackout.

Machined to precise military dimensions, this carbine buffer measures 3.25 inches in length and features internal steel weights paired with a rubber bumper to cushion bolt carrier impact and reduce wear on your receiver extension.

Finished in a durable matte black coating, it offers high resistance against friction and corrosion inside the buffer tube. Installation is 100% drop-in—simply slide it into your standard carbine receiver extension behind your carbine recoil spring to complete your lower receiver build or restore reliable operation to an existing rifle.
