Aero Precision Adjustable Low Profile Gas Block .625

This adjustable gas block from Aero Precision allows you to fine-tune gas flow to your AR-15's operating system, reducing felt recoil, minimizing port wear, and optimizing cycling with suppressed or unsuppressed fire. The low-profile design sits beneath most free-float handguards, and the adjustment screw lets you dial in the exact gas volume for your barrel length, ammunition, and shooting conditions. Particularly useful for tuning suppressed rifles or carbine-length systems that can be overgassed with factory settings.

Machined from steel with a nitride finish for corrosion resistance and heat tolerance. Fits standard .625-inch diameter barrels common on mid-length and carbine gas systems. Installation requires a barrel dimple or set screw alignment—consider professional installation if you're unfamiliar with gas block timing and torque specs. Includes adjustment screw and set screws for secure mounting.
