The Odin Works .300 Blackout Barrel in 16.1-inch Medium Profile Black (Odin Works part no. B-300-16-P-TG-BLK) is a bare AR-platform barrel machined from 416R stainless steel and hand lapped for a smooth, consistent bore. Odin Works cuts M4 feed ramps into the barrel extension and threads the muzzle 5/8-24, and the barrel ships with a black nitrided adjustable gas block already installed. At 16.1 inches, it clears the federal 16-inch rifle barrel minimum, so it drops straight onto a standard rifle-configured AR-15 build with no NFA paperwork required.
