The Guntec USA Low Profile Gas Block (brand part number GT750SS) is a .750-inch diameter steel gas block finished in matte black, built to sit flush under a rifle-length or carbine-length handguard instead of protruding above it. Steel construction handles the heat and pressure at the gas port better than a lighter aluminum block, and Guntec includes the roll pin needed for installation. It is made in the USA and sized to fit any barrel with a .750-inch gas block journal.
