Faxon Firearms Adjustable .625" Low Profile Gas Block - 3 Screw - 4140 Steel

The Faxon Firearms Adjustable .625" Low Profile Gas Block is a precision-machined AR-platform gas system component built for barrels with a standard .625" gas journal. Its low-profile footprint tucks cleanly under virtually any free-float handguard, and the 3-screw clamping design locks the block securely to the barrel for a rock-solid, repeatable install.

Faxon's patented adjustment screw is positioned out of the direct gas stream so it will not collect carbon fouling, keeping the mechanism free from seizing even under hard, sustained fire. With 14 tactile detent settings from fully open to fully closed, the block lets you dial in cycling behavior for suppressed shooting, subsonic loads, lighter bolt carrier mass, or simply to reduce felt recoil and wear.

The body is machined from 4140 steel and finished in black, weighing just 0.07 lbs with a footprint of roughly 1.00" wide by 1-7/32" tall. Installation uses an Allen-key interface on all three mounting screws, so no specialty tools are required. Like every Faxon component, this gas block is made in the USA and backed by the company's lifetime guarantee.
