Faxon Patented Adjustable .625" Low Profile Gas Block (3 Screw)
Overview
The Faxon Patented Low Profile .625" Adjustable Gas Block is built for shooters who want dependable tuning in both suppressed and unsuppressed setups—especially on lightweight barrel profiles that use a .625" gas journal. Faxon’s patented anti-fouling adjustment design places the adjustment screw so it does not contact gas-port carbon—helping prevent seizing and keeping adjustments consistent over time.
With 14 tactile settings from fully open to fully closed, you can fine-tune cycling and recoil for your exact barrel, ammo, buffer system, and suppressor combination.

Faxon adjustable gas block
I have not shot the rifle yet, but the installation was easy and straightforward. The workmanship is excellent! The design is smart. I have a couple of adjustable gas blocks from other companies and I will say at this point, I think that the Faxon adjustable gas block is going to be my go to. I ordered two .625 and installed one, at the time Faxon was out of stock on the .750, but since then was back in stock and I ordered two of them and are awaiting for their delivery. I can't wait to get to the range and get this adjusted, and give them a workout.

Adjustable gas block
First one of Faxtons I’ve used, tried it because I used their barrel and bcg on this build. Fit and finish are good, adjusts smoothly, running lightweight bcg with suppressor…..works good
