7.5 Inch .300 Blackout Barrel by AT3 Tactical

Made from 4150 CMV steel per Mil-B-11595E, and finished with a durable black nitride treatment, this barrel holds up under pressure, with excellent corrosion resistance. This barrel fits all your standard AR-15 uppers if you’re going for a fresh build, with M4 feed ramps for reliability.
This barrel uses a .750″ diameter gas block, plus a Pistol length gas tube, both of which you can snag here at a lower, bundled cost.
