Our low profile micro gas block is constructed of all steel construction. The low profile micro gas block replaces the existing A2 front sight, and is sleek and small to allow for the use of a longer rail. It can be used when installing a mid length, specter length or rifle length handguard to a shorter length gas system barrel. It is compatible with .308 and 5.56/.223 bull barrel with a .936 diameter barrel. Roll pin and set screws are included. No modification to your barrel is required.
