Proof Research PXT Terminus Apollo Carbon Fiber Prefit Barrel 6mm Creedmoor 18" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT Terminus Apollo carbon fiber prefit barrel is chambered in 6mm Creedmoor with an 18-inch length, Sendero contour, and a 1:7.5" twist. Featuring a carbon fiber finish, this barrel utilizes PXT (Proof Exponential Twist) rifling geometry, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the bore. This advanced design helps improve consistency, reduce felt torque, and extend barrel life while maintaining traditional lightweight carbon fiber performance.
