Phase 5 Hexone AR15 Rifle Buffer Tube Complete Assembly. CNC-machined in house from USA sourced 7075 aluminum. The HexOne-R features a hexagonal design that is thicker and rugged than a mil-spec receiver extension tube, making it perfect for rifle-length AR platform systems. All HexOne tubes undergo a rugged tumbling process that further strengthens the exterior of the parts while leaving the surfaces smooth and snag free. Edge to Edge OD: 1.4in. Flat to Flat OD: 1.25in. Note: This model of the Hex Tube lineup is not designed to accept a pistol brace. Includes: HexOne Rifle Length Buffer Tube, Castle Nut, End Plate. HexOne-R also includes Rifle buffer and rifle buffer spring. Fits Mil-Spec and Billet lower receivers just like a standard Tube! CNC-machined 7075-T7 billet aluminum Hexagonal buffer tube. Machined lower slot and anti-tilt technology built into every tube.
