POF's Mil-Spec 7075-T6 aircraft aluminum Anti-Tilt Buffer Tube uses a carrier cradle and 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. POF-USA's designing also features three (3) extra drain holes for marine environments.
