POF USA 6 Position Anti-Tilt Buffer Tube
In stock
$55.88POF’s 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 operating conditions. POF-USA’s design also features three (3) extra drain holes for marine environments.
- Replacement Compatible with All P415 and P416 rifles with 6 position buffer tube.
