Rosco Manufacturing
The Rosco 18" Purebred .223 Wylde precision rifle barrel is built for shooters who demand accuracy out of a mid-length platform. Whether you're building an SPR (Special Purpose Rifle), DMR (Designated Marksman Rifle), or a precision-focused AR-15, this barrel delivers the balance of weight, handling, and performance that serious marksmen rely on. The .223 Wylde chamber accepts both .223 Remington and 5.56 NATO ammunition, giving you flexibility at the reloading bench or the ammunition counter.
Rosco engineered the gas port sizing with precision shooting in mind—the ports are tuned to work reliably across popular bullet weights and with suppressor use, so you can shoot suppressed without sacrificing reliability or dealing with over-gassing. The 1:7 twist rate stabilizes a wide range of modern .223 projectiles, from lighter varmint rounds to heavier match-grade loads. Built from 416R stainless steel and finished with a durable bead-blasted surface, this barrel handles field use and bench shooting without flinching.
The rifle-length gas system and 1/2x28 threading give you solid platform compatibility and endless suppressor or muzzle device options. If you're assembling a duty rifle, competition build, or a long-range squirrel getter, a quality barrel is the foundation—and this one won't hold you back.
