Designed and built from scratch, each Purebred barrel starts as a blank made in-house from 416R stainless steel, before going through their entire manufacturing process. From stepped crown to barrel extension, the Purebred-series is meticulously cut and finished to offer out-of-the-box results that any shooter can appreciate.

High quality 416R stainless steel barrel blanks are produced in house and are the starting point for every Purebred AR-15 barrel. Each barrel is meticulously turned and polished, before being mated to their house-built barrel extensions, ensuring they have full control over the entire manufacturing in order to make sure each barrel meets their stringent quality standards. Whether you're building a hard-hitting precision carbine or well-balanced hunter without losing out on accuracy, the consistent performance of a Purebred barrel is just what you're looking for. For even better results, match it with a Purebred-series upper receiver!
This 10.5" barrel is machined to a heavy contour, offering exceptional rigidity. The 300 BLK chamber provides shooters with their choice of suppressed subsonic ammunition or hard hitting super-sonic options, with a reliable pistol-length gas system. An equally flexible 1:7 twist rate was selected to stabilize the full range of 300 BLK ammunition choices.
Rosco Manufacturing got their start producing high quality, hard-use precision rifle barrels. They have since expanded, offering their own line of serious use parts and accessories so you can assemble a rifle that doesn't just shoot good and look good, but will handle hard use as well. To top it off, they're production facility is in Central Falls, Rhode Island so you know that every component is 100% made in America, by Americans.
