CMMG Low-Profile Gas Block .936" Black Chrome Moly Steel

The CMMG Low-Profile Gas Block (part number 55DA36F) is a non-adjustable .936 inch inner-diameter gas block machined from durable 4142 chrome moly steel and finished in matte black, purpose-built for AR-platform barrel journals of that diameter.

The low-profile design sits close to the barrel so it stays clear of handguards and free-float tubes, making it a clean drop-in choice for a custom build or as a direct replacement on an existing rifle. A non-adjustable configuration keeps the gas system set-and-forget once the rifle is tuned.

Sold as a complete gas block assembly, the package includes the gas block and the installation screws needed to mount it to the barrel journal. Pair it with the appropriate length gas tube to complete your AR-platform gas system.
