The LBE Unlimited Mil-Spec 6-Position AR-15 Buffer Tube (brand part no. MBUF002-CG) is a receiver extension built to the mil-spec diameter rather than the larger commercial-spec size, so it works with the wide range of mil-spec collapsible stocks most AR-15 owners already run. Six adjustment positions let shooters set length of pull to match their build, body armor, or shooting stance. Finished in gray, it drops onto any standard AR-15 lower receiver to complete the buffer system.
