AR-15 Buffer Retainer
The AR-15 Buffer Retainer is a mil-spec replacement detent that holds the buffer and recoil spring inside the receiver extension when your upper is separated from the lower. Machined from hardened steel and built to standard AR-15 dimensions, it drops straight into the retainer pocket at the rear of the lower receiver without fitting or modification. Spring-loaded for positive engagement, this part is one of the most commonly lost components during a lower build or detail strip. A must-have spare for AR-15 builders, armorers, and anyone who keeps their own rifles running.
