The Ballistic Advantage BA Hanson 5.56 14.5-inch AR Barrel (brand part number BABL556008F) is a carbine gas system barrel machined from 4150 Chrome Moly Vanadium steel and finished in a corrosion-resistant QPQ coating. Ballistic Advantage’s Performance Series adds a nickel boron coated M4 feed ramp extension for smoother, more reliable feeding, and the proprietary BA Hanson profile balances weight with rigidity. It ships with a pinned, low-profile gas block sized for a 1.03-inch, .750-inch seat, and it’s built for direct impingement systems only, not aftermarket piston kits. Because it measures under 16 inches, federal law restricts this barrel to pistol-configured AR lowers, registered SBRs, or registered machine guns; it cannot legally be installed on a standard rifle-configured lower.
