Our 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. POF-USA’s designs also features three (3) extra drain holes for marine environments
I just can’t talk up enough POF Buffer tubes, I am tall and want a longer stock so I got this tube and coupled it with a MagPul MOE-SL stock. This combo is so solid and balanced that it impresses me every time I shoulder it. I can even set my gun, stock on the table, barrel in the air, and like a statue it does not move. This stock can use all 7 positions and when fully collapsed has plenty of room for a single point sling receiver end plate. O and so you know, this tube uses regular carbine length buffer and spring not rifle length. I must also mention the fact that similar anti tilt tubes cost much more $$$.
500 rounds and still working perfectly.
