The BCM Low-Profile Gas Block (brand part number BCM-LGB-750) gives a .750" barrel a mil-spec gas block sized to sit flush under a free-float handguard. Bravo Company Mfg builds it from steel and finishes it with a black phosphate coating, manufacturing it within very tight Mil-Std tolerances so it seats consistently and holds up to duty-cycle use. Its low-profile shape lets any rail system designed to install over the gas block sit close to the barrel, keeping the upper’s profile clean on a build focused on reliability over add-ons.
