Lead & Steel AR-15 5.56 13.9in Mid-Length Government Profile Barrel

Lead and Steel AR-15 Barrel Features The Lead and Steel AR-15 Barrel is machined from 4150 Chrome Moly Vanadium Steel a material prized in the AR-15 world for its strength and heat resistance under sustained firing. A QPQ Black Nitride finish is applied to both the bore and exterior offering superior corrosion resistance and surface hardness compared to a traditional phosphate coating. The Government profile keeps the barrel s exterior dimensions compatible with a wide range of standard handguards and gas blocks. M4 feed ramps are machined into the barrel extension area improving feeding reliability across different magazine types and ammunition. A 1-in-7 twist rate stabilizes a broad range of 5.56 bullet weights from lighter varmint loads up through heavier tracer and open-tip match projectiles. At 13.9 inches with a mid-length gas system the barrel strikes a balance between a shorter carbine-length rifle and a full 16 inch barrel offering good ballistics in a more compact package when paired with the correct gas system length. The mid-length gas system also tends to run softer than a carbine-length system reducing felt recoil and wear on parts over time.
