LBE Unlimited Mil-Spec 6-Position Buffer Tube for AR-15 in Black

The LBE Unlimited Mil-Spec Buffer Tube (brand part no. MBUF002) is a 6-position receiver extension built to mil-spec dimensions for standard AR-15 lowers. Because it matches mil-spec outer diameter rather than the slightly larger commercial-spec size, it works with the widest range of mil-spec stocks, buffers, and springs on the market. LBE Unlimited finishes the tube in black to match standard AR-15 hardware. It is a straightforward, compatible replacement for anyone building a lower receiver or swapping out a worn or damaged buffer tube.
