Faxon Firearms 3-Screw Low Profile Gas Block – .750" – AR-15

The Faxon Firearms 3-Screw Low Profile Gas Block provides a secure, no-frills solution for directing propellant gas from the barrel into the gas tube on AR-15 platforms. This block replaces factory front sight bases or clamp-on blocks, sitting beneath free-float handguards for a clean profile. The three-screw design distributes clamping force evenly around the barrel journal, reducing the risk of barrel dimpling or misalignment common with set-screw-only designs.

Machined from steel with a black finish to resist corrosion and heat discoloration. Fits barrels with a .750" gas block journal—verify your barrel diameter before ordering. Installation requires barrel dimpling or dimple-free installation if using proper torque specs and thread locker. A roll pin is included for gas tube retention. Drop-in for builders with basic armorer tools; gunsmithing recommended for first-time installers to ensure proper gas tube alignment and headspace.
