Description
Elevate your AR-15 build with the PROOF Research PR15 barrel in 223 Wylde chambering — a precision-engineered carbon fiber wrapped barrel designed for shooters who demand accuracy, consistency, and reduced weight without compromise. The 18-inch profile with an 8-twist rate stabilizes a wide range of projectiles, making it equally at home on the competition stage or in the field. The PXT (Patented PROOF Carbon Fiber Wrapped) construction delivers exceptional heat dissipation and dramatically reduced barrel weight compared to traditional steel profiles, all while maintaining the rigidity and accuracy that PROOF Research is renowned for worldwide.
The 223 Wylde chamber is the ideal choice for AR-15 builds, offering the accuracy benefits of a .223 Remington match chamber while maintaining safe, reliable feeding and function with standard 5.56 NATO ammunition. Whether you’re building a precision bolt rifle, a long-range AR platform, or a dedicated competition rifle, this barrel delivers the performance you expect from one of the most respected names in precision barrel manufacturing.
