Proof Research’s 264 Caliber 24 Inch Carbon Fiber Sendero Light Bolt Action Barrel starts with a full-profile, match-grade 416R stainless steel blank that is precision-turned and wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. The barrel incorporates a 7.5 twist rate and Sendero Light contour, with a weight of just 2 lbs 15 oz for shooters and hunters who require maximum accuracy without unnecessary bulk.
The carbon fiber construction transfers heat very effectively through the barrel wall, greatly increasing heat transport for faster cooling, sustained accuracy through extended firing, and extended barrel life. Proof Research applies single-point cut rifling to all its barrels, followed by lead lapping and rigorous inspection across multiple quality control stations throughout manufacturing. This precision method delivers the match-grade accuracy and consistency that serious shooters demand.
This barrel is up to 64% lighter than traditional steel barrels of comparable contour, making it well-suited for precision rifle builds where weight reduction directly improves field performance. The 24-inch barrel length delivers excellent velocity and ballistics while preserving the lightweight advantage of carbon fiber construction. As a barrel blank, it arrives ready for your gunsmith to thread and chamber to your specifications.
