.625" Ultra Low-Profile Gas Block
Perfect for any rail system, these ultra-low profile gas blocks are the ideal companion for Faxon Firearms (or any other) barrels with a standard diameter gas journal. Made from high-strength steel, all our gas blocks are a matching black luster to our barrels.
For lightweight builds, the block is drilled through the middle of the profile. The gas block clamps on to the barrel using 3 allen keys on the bottom of the block.
*Faxon Firearms highly recommends the use of Loc-Tite or similar thread-locking compounds. Gas blocks will get very hot, so pick a compound according to your intended use of the firearm.
- Barrel Compatibility: .625"
- Weight: .07 Lbs
- Width: 1.00"
- Height: ~1 & 7/32"
- Mounting: 3x Screws (Allen Key interface)
Gas block does not include the gas tube roll pin. Faxon includes gas tube roll pins with gas tubes.

Super low and light weight, having three set screws instills much confidence as well!
Nice machine work on this gas block
Fits great under my G3 light weight MI rail
Great fit, lightweight.
I found this gas block to be light in weight, a good snug fit, and also I like the triple locking set screws at the bottom to ensure it stays on.
I installed this on one of their pencil barrels.
It is so light weight ,these two products ( Faxon pencil Barrel, and low profile gas block) made an awsome build.
I look forward to using more of their products in the future.
