Faxon Firearms
The Faxon Firearms Low Profile .750 Lightweight Gas Block is a minimalist gas block designed for AR builders who want to shed weight without sacrificing reliability. Built from high-strength steel with a matching black luster finish, this .750 gas block clamps directly onto standard-diameter gas journals using three socket-head screws accessed from underneath the block. The low-profile design keeps your handguard clearance tight and your build sleek, while the through-drilled center reduces unnecessary mass—ideal for hunters and competition shooters building lightweight uppers that don't feel like a club at the end of a 12-mile hike.
This gas block works with Faxon barrels and any other rifle barrel sporting a standard .750 gas journal diameter. The clamping design means no permanent modifications to your barrel; you can swap it to another upper if your plans change. Because gas blocks live in the heat of the action, Faxon recommends locking down the screws with a thread-locking compound like Loc-Tite—the formula you choose should match your rifle's intended duty (lower temps for a competition gun, higher temps for a hard-use hunting rig that sees sustained shooting).
Whether you're assembling a lightweight hunting rifle, an ultra-portable truck gun, or a precision range rig, the Faxon low-profile gas block delivers the simplicity and weight savings builders expect from Faxon's line. Its compact footprint pairs naturally with any free-float rail system, and the no-frills clamping design means straightforward installation and adjustment.

Yes, if your barrel has a standard .750" gas journal diameter. The Faxon gas block clamps onto that journal and works with Faxon barrels as well as most other quality AR barrels with the same gas port size.
The low-profile design and through-drilled center eliminate material that doesn't contribute to function, cutting weight without weakening the block. This makes it ideal for builders prioritizing a lightweight, maneuverable rifle.
Yes. The low-profile design is engineered to work with standard rail systems, including free-float handguards, with minimal interference.
Faxon strongly recommends using a thread-locking compound like Loc-Tite on the three clamping screws. Choose a formula rated for your intended use—lower-temp compound for target shooting, higher-temp for hard-use rifles that see sustained fire.
