Proof Research PXT PR15 AR-15 Barrel 223 Wylde 16" Standard Contour 1:7" Twist Carbon Fiber

Overview

The Proof Research PXT PR15 AR-15 Barrel is a 16-inch standard contour barrel chambered in 223 Wylde with a 1:7" twist rate and a carbon fiber finish. Utilizing PROOF Exponential Twist (PXT) technology, this barrel features a complete rethinking of conventional rifling geometry and twist progression designed to reduce engraving force, minimize throat erosion, and create a smoother transition as projectiles engage the rifling. PXT technology helps reduce wear, improve consistency, and lower felt torque for better recoil control and target retention. The carbon fiber construction makes the barrel up to 64% lighter than traditional steel barrels of similar contour while offering match-grade accuracy, improved heat dissipation, reduced harmonic vibration, and no point-of-impact shift during high-volume fire.
