Overview
The Rosco Purebred 6mm ARC rifle barrel is engineered to maximize ballistic performance and precision. Featuring a 20-inch length and a durable stainless steel construction with a nickel boron finish, this barrel is built for consistency in demanding field and range environments. It utilizes an SPR contour that balances weight (42.80 oz) and rigidity, making it well-suited for both precision cold bore shots and rapid follow-up engagements. The 1:7.5-inch twist rate and Rifle +1 gas system are optimized to handle popular precision bullet weights effectively, while accommodating suppressor use. The muzzle is threaded with a 5/8"x24 pattern, providing seamless compatibility with a variety of muzzle devices and suppressors on standard AR platforms.
