Patriot Ordnance Factory AR-15 Six Position Buffer Tube Anti-Tilt

The POF-USA 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. Furthermore, the buffer-detent button doubles as a lock that stops the buffer tube from rotating and becoming loose under extreme operation conditions. The anti-tilt buffer tubes also feature three (3) extra drain holes for marine environments.
