Faxon .625 in 3-Screw Low-Profile Gas Block

The Faxon .625 in 3-Screw Low-Profile Gas Block is sized for AR-15 barrels with a .625 in gas-block journal. Three set screws secure the low-profile block in place, and the black matte finish keeps the component visually subdued under a handguard. The compact profile is intended for installations where clearance around the gas block is limited.

Gas-block diameter must match the barrel journal, so the .625 in inside diameter is the first specification to verify. The three-screw layout provides multiple contact points along the bottom of the journal while keeping the overall block shape simple. Alignment with the barrel gas port should be checked carefully during installation so the gas system can operate as intended.

This Faxon gas block is a straightforward option for lightweight or slim-profile AR-15 barrels using the .625 in journal size. Its low-profile body is designed to fit beneath compatible free-float handguards without adding an external sight tower. Browse more gun parts and accessories for gas-system and AR-15 components.
