Tune your AR with the Faxon Firearms patented adjustable .625″ low profile gas block featuring anti-fouling adjustment design, 14 tactile settings, and 3-screw mount. 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 positions the adjustment screw to avoid contact with gas-port carbon, which helps prevent seizing and maintains consistent adjustments over time. The gas block offers 14 tactile settings spanning fully open to fully closed, allowing you to fine-tune cycling and recoil for your specific barrel, ammo, buffer system, and suppressor combination. Adjustment can be made with either a 3/32″ Allen key or a flathead screwdriver.
Constructed from durable steel with a low-profile design and black luster finish, this gas block is engineered for light barrels with a standard diameter gas journal. The drilled center profile keeps weight minimal while three Allen screws provide secure barrel clamping for reliable attachment. Faxon Firearms products are backed by the Faxon Lifetime Guarantee to the original purchaser against defects in materials and workmanship.
