Patriot Ordnance Factory 00342 Buffer Tube Anti-Tilt AR-15 Mil-Spec 7075 T6 Aluminum 8.2" X 4" X 4" The Mil-Spec 7075-T6 aircraft aluminum Anti-tilt Buffer Tube uses carrier cradle extensions to ensure that the carrier is always supported by the buffer tube, even when the bolt is forward. This prevents carrier-tilt and premature wear on the buffer tube. Thusly, the buffer-detent button doubles as a lock that stops the buffer tube from rotating and becoming loose under extreme operation conditions. Type: Buffer Tube Model: AR-15 Dimensions: 8.2" x 4" x 4" Size: Mil-Spec Material: 7075 T6 Aluminum Finish: Black
