Proof Research PXT PR15 AR-15 Barrel 223 Wylde 14.5" Standard Contour 1:7" Twist Carbon Fiber

Overview

The Proof Research PXT PR15 barrel features proprietary Exponential Twist (PXT) technology, which utilizes advanced rifling geometry and twist progression to reduce engraving force and minimize throat erosion. By smoothing the projectile's engagement into the bore and reducing the rifling lead angle, this .223 Wylde chambered barrel improves consistency, reduces felt torque, and enhances barrel life. Constructed with a carbon fiber finish, the barrel features a 14.5-inch length and a 1:7 twist rate. It is designed for high-performance gas gun applications, offering match-grade accuracy, improved heat dissipation, and reduced harmonic vibration compared to traditional steel barrels. The barrel arrives fully chambered and ready for installation with a mid-length gas system, a .750-inch gas journal, and 5/8-24 muzzle threads.
