Proof Research Carbon Fiber AR-15 Barrel .223 Wylde 14.5" 1:7 Twist Mid-Length Gas PXT

The Proof Research Carbon Fiber AR-15 Barrel is chambered in .223 Wylde and engineered for lightweight performance and precision accuracy in modern sporting rifle platforms. This configuration features a 14.5-inch length with a 1:7 twist rate optimized for stabilizing heavier .223 Remington and 5.56 NATO projectiles, while maintaining versatility across a broad range of bullet weights. The .223 Wylde chamber allows safe use of both .223 Rem and 5.56 NATO ammunition while maximizing accuracy potential. Precision 5-groove rifling is designed to improve bore consistency and reduce fouling accumulation during extended use.

Built around Proof Research PXT carbon fiber technology, the barrel utilizes a match-grade steel core wrapped in aerospace-grade carbon fiber to improve stiffness-to-weight ratio, thermal stability, and heat dissipation. Technical specifications include a 5/8x24 threaded muzzle for suppressor or muzzle device compatibility, a mid-length gas system for smoother cycling characteristics, and a .750 gas block journal for broad compatibility with AR components. Designed for lightweight duty rifles, precision AR builds, and suppressor-ready setups, this barrel delivers reduced front-end weight with premium accuracy and durability.
