Lead & Steel AR9 300 Blackout 16" Government Profile Threaded Barrel

Lead & Steel AR9 Barrel Features The Lead & Steel AR9 Barrel is turned from 4150 Chrome Moly Vanadium steel a material chosen for its ability to withstand sustained heat and pressure without losing dimensional stability. A QPQ black nitride finish is applied over the steel adding a hard corrosion-resistant surface that also reduces friction during cycling and cleaning. The government profile gives the barrel a heavier contour along its length adding rigidity that helps maintain consistent accuracy as the barrel heats up during strings of fire. At 16 inches this barrel suits standard rifle-length AR builds chambered in .300 AAC Blackout where a full-length barrel is preferred over a compact pistol configuration. A 1:7 twist rate is matched to the heavier longer bullets often loaded in .300 AAC Blackout giving the barrel the stabilization needed across both supersonic and subsonic loadings. The 5/8x24 threaded muzzle accepts standard .30 caliber muzzle devices compensators or suppressors without requiring any additional machining. Weighing 29.60 oz the barrel adds a reasonable amount of mass to the front of a build without becoming unwieldy. For builders assembling or upgrading a 16 inch .300 AAC Blackout AR rifle who want a durable nitride-finished barrel the Lead & Steel AR9 Barrel is available for sale at ARMSAGORA.
