The Rosco Manufacturing Purebred 16" 6mm ARC barrel is precision-engineered to maximize the performance potential of the 6mm Advanced Rifle Cartridge. Built with a 416R stainless steel core and finished in a durable Nickel Boron coating, this barrel delivers exceptional accuracy and corrosion resistance. The SPR (Special Purpose Rifle) contour strikes an ideal balance between mass and rigidity, making it well-suited for cold bore precision shots without adding unnecessary weight. Gas ports have been carefully sized to accommodate the most popular precision bullet weights as well as suppressor use, ensuring reliable cycling across a variety of loads. The Rifle Length Gas System further contributes to a smooth, controllable shooting experience. Threaded at 5/8"x24 for standard muzzle device and suppressor compatibility, this barrel is a serious upgrade for any 6mm ARC AR-platform build.
