Proof Research PXT PR15 AR-15 Barrel 223 Wylde 11.5" Standard Contour 1:7" Twist Carbon Fiber

Overview

The Proof Research PXT PR15 AR-15 Barrel is an 11.5-inch carbon fiber barrel chambered in .223 Wylde featuring a standard contour and a 1:7-inch twist rate. Utilizing PROOF Exponential Twist (PXT) technology, the barrel incorporates a rethinking of conventional rifling geometry and twist progression designed to reduce engraving force, minimize throat erosion, and smooth projectile engagement into the bore. This design helps reduce wear, improve consistency, and lower felt torque for better recoil control and target retention. The carbon fiber construction makes it up to 64% lighter than traditional steel barrels of similar contour while offering match-grade accuracy, improved heat dissipation, reduced harmonic vibration, and freedom from point-of-impact shift during high-volume fire.
