Proof Research's 26-inch Sendero contour barrel for 264 Winchester Magnum bolt actions combines 416R stainless steel with aerospace-grade carbon fiber wrapping for reduced weight, superior heat dissipation, and match-grade accuracy.
Proof Research has built a reputation for uncompromising barrel quality, and this 264 Winchester Magnum barrel blank exemplifies that commitment. Designed for the serious rifleman who demands both performance and reliability, this barrel combines proven metallurgy with advanced composite technology.
The barrel starts as a full-profile, match-grade 416R stainless steel blank manufactured in Proof's own firearms division. The steel is then precision-turned to the Sendero contour—a profile that balances weight reduction with structural integrity. This foundation is then wrapped in aerospace-grade carbon fiber impregnated with Proof's proprietary matrix resin, developed by their advanced composites division.
Heat Management: The carbon fiber composite excels at diffusing and transporting heat away from the barrel wall, maintaining consistent performance during extended shooting sessions and reducing thermal distortion.
Weight Reduction: The carbon fiber wrapping significantly reduces overall barrel weight compared to traditional steel barrels of equivalent strength, making your rifle more manageable in the field.
Accuracy: This barrel delivers match-grade precision comparable to the finest all-steel barrels, with the added benefits of superior heat dissipation and reduced weight.
Durability: Built to withstand demanding conditions, this barrel is engineered for long-term reliability in competitive shooting, hunting, and tactical applications.
This barrel blank is ready for professional gunsmithing and installation into your custom rifle build.
