Bravo Company .625 in Low-Profile Gas Block

The Bravo Company .625 in low-profile gas block is sized for AR barrels with a .625 in gas-block journal. Its compact exterior is intended to fit beneath many free-float handguards while providing the fixed mounting point that directs gas from the barrel into the rifle’s gas system. The low-profile configuration is especially important on slim rails where a larger front-sight-style block would not clear the inside of the handguard.

Gas-block diameter must match the barrel journal exactly, so this .625 in model should not be substituted for a .750 in or other journal size. Alignment over the barrel gas port, gas-tube fit, and secure installation all affect reliable cycling and should be checked carefully during assembly.

This component is best suited to builds where a conventional low-profile block is required under the rail. Before tightening the block, verify that the gas tube moves freely through the upper receiver and that the block is centered over the gas port. A qualified gunsmith should handle the installation if barrel dimpling, pinning, or gas-system alignment is unfamiliar.
