The Proof Research 103548 Carbon Fiber Bolt-Action Barrel, .224 Caliber, 24" Sendero Contour is built for shooters who want match-grade precision without the bulk of a traditional steel barrel. This barrel starts with a premium 416R stainless steel blank that is turned down to a reduced profile and then wrapped in aerospace-grade carbon fiber, delivering excellent rigidity and heat management at a significantly lighter weight. Its 24-inch Sendero contour and 1:8 twist rate are optimized to stabilize modern .224 caliber projectiles for consistent accuracy at extended ranges.

With a 2.5-inch breech length and 1.20-inch shank diameter, this barrel blank is ready for your gunsmith to thread and chamber to your preferred .224 cartridge, making it ideal for custom precision rifle builds. The 3 pounds 4 ounces weight helps maintain a balanced rifle that is comfortable for long days at the range, varmint hunting, or precision target work. Proof Research’s advanced composite construction and attention to detail result in a barrel that combines durability, accuracy, and innovation for demanding shooters.
