Proof Research Sendero Carbon Fiber Barrel Blank Features The Proof Research Sendero Carbon Fiber Barrel Blank is engineered around PXT PROOF s Exponential Twist rifling geometry which dramatically reduces rifling lead angle and smooths projectile engagement into the bore. This reduces engraving force minimizes throat erosion and creates less felt torque during firing improving recoil control and the ability to stay on target shot after shot. In controlled testing PXT barrels have demonstrated a 30 to 100 percent increase in barrel life while maintaining the accuracy standards expected from a Proof Research barrel. The 24 length and 1:8 twist rate in .284 Caliber are matched to the Sendero contour a profile chosen for its balance of stiffness and manageable weight on a custom rifle build. Carbon fiber construction delivers an exceptional stiffness to weight ratio reducing overall rifle weight without sacrificing the barrel s stability or accuracy potential. At 2 lbs 13 oz this blank is dramatically lighter than a comparable steel barrel a meaningful advantage for hunters who carry their rifle over long distances. Designed for custom rifle builders and gunsmiths the blank offers a premium foundation for lightweight hunting rifles precision long range systems and modern high-performance rifle builds.
