The Lead & Steel LS556GOV-MID-13.9 5.56mm AR-15 barrel is built around a proven government profile and mid-length gas system, offering a balanced blend of rigidity and manageable weight. Turned from durable 4150 chrome moly vanadium steel and finished in a QPQ black nitride coating, this 13.90" barrel is designed for long service life and consistent performance. M4 feed ramps and a 1:7" twist rate support reliable feeding and stabilization of a wide range of 5.56x45mm NATO loads.

This barrel is well suited for building a compact, general-purpose AR-15 that sees regular range use, training, or practical competition. The mid-length gas system helps maintain smooth cycling and controllable recoil, while the threaded muzzle allows the use of common flash hiders or muzzle devices. Lead & Steel is known for producing thoughtfully spec’d components that emphasize durability and straightforward craftsmanship.
