Proof Research PXT PR15 AR-15 Barrel 223 Wylde 18" Standard Contour 1:8" Twist Carbon Fiber

Overview

The Proof Research PXT PR15 is an 18-inch AR-15 barrel featuring a carbon fiber finish and chambered in .223 Wylde. These barrels utilize PXT (PROOF Exponential Twist) technology, a rifling design engineered to reduce engraving force and minimize throat erosion. By smoothing the transition as the projectile engages the rifling, this technology helps reduce wear, improve consistency, and lower felt torque for better recoil control. These barrels offer match-grade accuracy and are up to 64% lighter than comparable steel barrels. The construction provides improved heat dissipation, which allows for consistent performance without point-of-impact shifts during high-volume fire. The barrels are fully chambered and ready for installation.
