Patriot Ordnance Factory Buffer Tube for 223 Rem AR-Style, Anti-Tilt, Black, Aluminum

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. The buffer-detent button doubles as a lock that stops the buffer tube from rotating and becoming loose under extreme operation conditions.
