Most Helpful Positive Review One of the most basic thing anyone could come up with and for some reason no one did until now
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.
Most Helpful Negative Review gas block bent and warped
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

Faxon adjustable gas block

by Babayaga, Verified Owner from GA, United States Written on December 1, 2025
I have two, one on a DD UPPER and one on an aero upper, both of which I run suppressed. Over 2000 rounds through both gas blocks and no issues. Adjustment screw never moves due to recoil but never locks up due to carbon. I can’t recommend this enough, just make sure you install it correctly and red loctite the screws. You can’t blame the product for bad installation. Mine has never come loose.

Fits great on AR10

by Neil C, Verified Owner from OR, United States Written on 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.

Great product by Faxon as always

by Draeco, from GU, United States Written on October 26, 2025
What else is there to say? It does what it describes. After 1000+ rounds, the adjustment screw did not move to another setting.

Everything promised on this adjustable gas block was right on spot. Made my gun shot perfectly with the suppressor . A little time figuring out the right adjustment but well worth it.

Cleaner and easier

by ShotDoc, Verified Owner from AZ, United States Written on 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.
Pros:
  • Very easy to adjust. Fouling miuch lets significant.
  • Fouling much less significant. Easy to adjust through 14 settings.
  • Fouling is much less of a factor with this design. Very easy to adjust through 14 settings.
Cons:
  • None that I have found yet.
Would recommend: Yes
