The Proof Research 223 Wylde 1-8 Twist 14.5" Carbon Fiber Barrel brings match-grade precision to the AR-15 platform in a remarkably lightweight package. Built around a stainless steel core wrapped in carbon fiber, this 14.5-inch, 1:8 twist, mid-length gas barrel is threaded 1/2x28 at the muzzle for easy attachment of your preferred device while maintaining excellent balance and handling.

This barrel is ideal for shooters who want to cut weight without sacrificing accuracy or durability, whether for extended range sessions, competition, or a fast-handling carbine build. The carbon fiber construction improves heat dissipation and helps the barrel stay cooler during strings of fire, supporting consistent performance shot after shot. It is purpose-built for the .223 Wylde chamber, offering reliable use with both .223 Remington and 5.56 NATO ammunition, and reflects Proof Research’s focus on innovation and precision manufacturing.
