Lead & Steel AAC Blackout 10.5in Government Profile Barrel 1:7 Twist

Lead & Steel Barrel Features The Lead & Steel AAC Blackout Government Profile Barrel is machined from 4150 Chrome Moly Vanadium Steel a material chosen for its strength and heat resistance under sustained firing. Its government profile adds material along the barrel for extra rigidity and better heat dissipation compared to a lighter contour which helps maintain accuracy as the barrel warms up. A 1 in 7 inch twist rate is matched to the .300 AAC Blackout cartridge s wider range of bullet weights stabilizing both lightweight supersonic loads and heavier subsonic rounds. M4 feed ramps are cut into the barrel extension to improve feeding reliability across a variety of magazines and ammunition types. A QPQ Black Nitride finish coats the barrel inside and out providing corrosion resistance and a slick surface that eases cleaning and reduces fouling buildup. The 5/8x24 thread pattern at the muzzle accepts standard .30 caliber muzzle devices giving builders the option to add a brake comp or suppressor mount. At 10.5 inches this pistol length barrel suits a compact AR pistol build intended for maneuverability without sacrificing the ballistic advantages of the .300 AAC Blackout platform. Backed by Lead & Steel s attention to material and finish this barrel is a solid foundation for a reliable AR-15 pistol build.
