PROOF Research PXT .308 20″ Carbon Fiber Sendero Barrel

The PROOF Research PXT .308 20" Carbon Fiber Sendero Barrel combines cutting-edge rifling technology with the renowned lightweight performance of PROOF barrels. This barrel features the innovative PXT (PROOF Exponential Twist) design, which reimagines traditional rifling geometry to reduce engraving force, minimize throat erosion, and provide a smoother transition as the projectile engages the rifling.

Key Features

• 20-inch carbon fiber barrel with Sendero contour
• PXT technology for reduced wear and improved consistency
• Exceptional stiffness-to-weight ratio
• Lightweight at 2 lbs 11 oz
• Shank diameter of 1.20 inches

The PXT technology dramatically reduces rifling lead angle, enhancing recoil control and allowing for better target retention. In testing, PXT barrels have shown a 30-100% increase in barrel life while maintaining the precision synonymous with PROOF barrels.

Designed for custom rifle builders and gunsmiths, this barrel blank is an ideal choice for crafting lightweight hunting rifles, precision long-range systems, and high-performance rifle builds where durability and consistency are paramount.
