The PROOF Research PR15 Carbon Fiber Wrapped Barrel in 223 Wylde chambers the best of both worlds: the precision of match-grade stainless steel combined with the rigidity and dramatic weight reduction of a carbon fiber wrap. Designed for the AR-15 platform, this 18-inch barrel features a 1:8 twist rate optimized for stabilizing a wide range of .22-caliber projectiles, from lightweight varmint rounds to heavier match bullets. The PXT (Performance Xtreme Technology) profile delivers exceptional stiffness-to-weight ratio, reducing barrel harmonics and improving shot-to-shot consistency. The 223 Wylde chamber is cut to tight tolerances, offering exceptional accuracy with both .223 Remington and 5.56 NATO ammunition. Whether used for precision long-range shooting, competition, or a high-performance build, this PROOF Research barrel represents the pinnacle of modern rifle barrel engineering.
