This carbon fiber barrel has a 1.20″ shank diameter and 2.5″ breech length, weighing just 2 lbs 10 oz. Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, it delivers exceptional performance in a lightweight package.
The advantages of Proof Research’s patented carbon fiber technology are substantial. These barrels are up to 64% lighter than traditional steel barrels of similar contour, with improved heat dissipation for cooler and longer lasting barrels. The patented process produces barrels that are stiffer with less harmonic vibration than steel, dissipate heat more quickly resulting in maintained accuracy over longer sessions of fire and longer barrel life, while being as accurate as the finest precision steel barrels. The Sendero Light contour design provides excellent balance between handling ease and rigidity for consistent accuracy.
Ideal for precision rifle builds, this barrel is shipped ready for your gunsmith to thread and chamber to your specifications. Perfect for long-range competition, hunting, or precision shooting applications where reduced weight and superior thermal management make a measurable difference in performance and barrel longevity.
