Faxon Firearms Adjustable 3-Screw Low Profile Gas Block – .625" Diameter

The Faxon Adjustable 3-Screw Low Profile Gas Block gives you precise control over your AR-15's gas system. This gas block allows you to tune your rifle's cycling for suppressed shooting, different ammunition loads, or to reduce felt recoil and port pressure. The adjustable design is particularly useful when running a suppressor, where excess gas can cause overgassing and accelerated wear on components.

Machined from steel with a low-profile design that fits under most free-float handguards, this gas block uses three set screws for secure barrel mounting. The adjustment screw is accessible from the front, allowing you to dial in gas flow without removing the handguard on most setups. Installation requires proper alignment and torque—while mechanically straightforward, shooters unfamiliar with gas system work should consider professional installation to ensure correct headspacing and function.
