Helpful Positive Review
I have a Tailhook brace and this buffer tube was right on. The fact that it is the harder Aluminum (7075?) sold me. Fits my Aero Precision lower perfectly as the threads are sharp. The Foam padding is nice also.

pistol brace upgrade by Wilson Mylum, Verified Owner, March 29, 2025
This buffer tube looks awesome and does the job it is designed for. The added hexagonal shape just adds to the aesthetic of a typical cylindrical tube but nothing for function.

Phase 5 Hex 2 by Warrior, Verified Owner, January 31, 2025
Best standard length tube on the market for Tailhook. Keeps pistol short enough to be under 26”.

Solid brace arm by Nick, January 16, 2024
Solid, good length of pull. Good finish. The hex "edges" aren't rough on your fact and unlike other tailhook brace arms, there are no jank holes or grates to snag on your beard.

Great buffertube by P, Verified Owner, September 23, 2022
Awesome buffertube! The hexagon design gives it a unique look and is built solid! I went with this one because it’s made. specifically for the tailhook mod 1 brace (which it worked perfectly for!) Definitely recommend!

Good option for Kriss Vector by Ryan, Verified Owner, February 13, 2022
The tube is well made and fits great on my vector. I purchased this for a Tailhook brace that I’m still waiting on, but I’m happy with my choice vs a round tube. Only thing to note - there isn’t a drainage hole at the end of the tube, if that matters...
