gas block bent and warped by Billy, Verified Owner, October 30, 2025
This gas lock gave me issue from the beginning. It would move position to become more and more under gassed. Eventually after this last range day it warped completely and broke. I do NOT recommend

This is the only gas block you would need. Everything else is inferior. Believe me. Haven't shot enough yet to really test and see it's shortcomings but it's super promising.

Cleaner and easier by ShotDoc, Verified Owner, July 26, 2025
Much more easy to adjust, with 14 different positions. Also, importantly, this design fouls much less than others, and mounting is very easy and very secure with the three set screws across the bottom.

Fits great on AR10 by Neil C, Verified Owner, October 29, 2025
Haven’t tested yet but so far fits and looks great. Gas tube can be a little difficult to install since the adjustable part of the gas block can slip off but it’s not to bad with the right tools.

What else is there to say? It does what it describes. After 1000+ rounds, the adjustment screw did not move to another setting.

Faxon Adjustable Gas Block . 750" by McNally, Verified Owner, October 22, 2025
OP shipped the order out really quickly. Packed well. The gas block installed without problem. I had it adjusted to give a 3:30-4:00 ejection in 6 rounds from fully closed. Well made, works perfectly.
