The Proof Research 223 Wylde 1-8 Twist 16" Carbon Fiber Barrel brings match-grade performance to the AR-15 platform in a lightweight, heat-dissipating design. Built around a full-profile 416R stainless steel blank that is turned down and wrapped in aerospace-grade carbon fiber, this barrel is engineered to deliver precision accuracy while significantly reducing overall rifle weight. The 16" length with 1/2-28 threaded muzzle makes it ready for your preferred muzzle device or suppressor-compatible brake.

This 223 Wylde barrel is optimized for mid-length gas systems, offering a smooth recoil impulse and reliable cycling with a wide range of .223 Remington and 5.56 NATO loads. The medium contour and carbon fiber wrap help manage barrel harmonics and heat, supporting consistent point of impact during extended range sessions or training days. Ideal for precision-focused AR builds, competition use, and general range shooting, it reflects Proof Research’s reputation for combining advanced composites with meticulous barrel craftsmanship.
