Proof Research Carbon Fiber Barrel Blank .224 Caliber 16.5" 1:8 Twist Sendero Contour

The Proof Research Carbon Fiber Barrel Blank is a premium match-grade barrel designed for custom bolt-action rifle builds chambered in .22 caliber cartridges. This configuration features a compact 16.5-inch length with a 1:8 twist rate, making it ideal for stabilizing a wide range of modern .224 caliber projectiles, including heavier, high-ballistic-coefficient bullets favored for precision shooting and hunting. Precision 4-groove rifling promotes exceptional bore consistency, reduced fouling, and outstanding shot-to-shot accuracy, while the Sendero contour provides increased rigidity and harmonic stability without the weight penalty of a traditional steel barrel.

Built around a match-grade stainless steel core wrapped in aerospace-grade carbon fiber, the barrel blank delivers an exceptional stiffness-to-weight ratio, enhanced thermal stability, and reduced point-of-impact shift during prolonged shooting sessions. As an unfinished barrel blank, it is intended for professional gunsmiths and custom rifle builders to chamber, thread, and fit to the desired bolt-action receiver and cartridge. The compact 16.5-inch length makes it particularly well suited for suppressed rifle builds, lightweight hunting rifles, and compact precision platforms where maneuverability and weight savings are critical.

Designed for shooters and builders who demand premium materials and uncompromising performance, this Proof Research carbon fiber barrel blank provides the ideal foundation for a lightweight, highly accurate custom rifle.
