Geissele Automatics Premium Mil-Spec AR-15 Buffer Tube - 7075-T6 Aluminum - Black

The Geissele Automatics Premium Mil-Spec Buffer Tube is a heavy-duty receiver extension purpose-built for the AR-15 / M4 platform. Machined from 7075-T6 aluminum and finished in a rugged Type III hardcoat anodized black coating, this buffer tube delivers the strength, dimensional consistency, and corrosion resistance AR builders expect from a premium component.

Cut to true Mil-Spec diameter, the tube is fully compatible with all standard carbine-length buffer components, castle nuts, and end plates. It features the conventional 6-position adjustment detents used by most adjustable stocks and pistol stabilizing braces, giving the shooter a wide range of length-of-pull options while maintaining a secure lock-up at each position.

At 3.7 oz and a length of 14.75", the Geissele Premium Mil-Spec Buffer Tube is dimensionally identical to GI tubes for true drop-in installation on any Mil-Spec AR-15 lower receiver, and is also reported compatible with AR-308 pattern builds. Whether you are completing a new build or upgrading an existing rifle, this tube provides the rock-solid foundation needed for reliable cycling and stock fitment.
