Rosco Purebred 6mm ARC 20" Nickel Boron Stainless Barrel

Rosco Purebred Barrel Features The Rosco Manufacturing Purebred Barrel is chambered in 6mm ARC and built with an SPR contour a profile chosen specifically to balance weight savings against the barrel stiffness needed for consistent repeatable cold bore accuracy. Machined from stainless steel and finished with a nickel boron coating the barrel resists corrosion while providing a smooth low-friction bore surface that can ease cleaning and reduce fouling buildup over time. A 1:7.5 inch twist rate is matched to stabilize the heavier high ballistic coefficient bullets that have made 6mm ARC popular among precision rifle shooters. Gas ports are sized specifically around the most common precision bullet weights as well as suppressed use ensuring reliable cycling across a range of loads. At 20 inches long and threaded 5/8x24 the Purebred Barrel is ready to accept a suppressor or muzzle device out of the box. The barrel runs on a Rifle Length Plus 1 gas system a configuration chosen to soften the recoil impulse and improve reliability when the rifle is run suppressed. Weighing 42.8 ounces this barrel is a meaningful upgrade over many factory 6mm ARC barrels in both finish and performance. The Rosco Manufacturing Purebred Barrel is for sale at ARMSAGORA for precision shooters looking to build or upgrade a 6mm ARC rifle for improved accuracy and suppressor compatibility.
