Proof Research 264 Caliber 1-8 Twist 24'' Carbon Fiber Bull Barrel

The Proof Research 264 Caliber 1-8 Twist 24" Carbon Fiber Bull Barrel is a precision rifle barrel built for hunters and long-range shooters who demand lighter weight without sacrificing accuracy or durability. This 264 caliber barrel comes pre-fitted with a 1-8 twist rate and a 24-inch profile, ready for your gunsmith to thread and chamber to your exact specifications. Proof Research has engineered these carbon fiber barrels to deliver measurable advantages over traditional steel—10 times stronger by weight, yet up to 64% lighter—making them ideal if you're building a rifle that needs to shoot far without dragging hard across rough country.

Carbon fiber construction means your barrel resists the environmental damage that can degrade steel. Nicks, dings, and weather won't compromise the exterior, and the material's superior heat dissipation keeps your barrel cooler during sustained fire. That cooling effect translates directly to longer barrel life and more consistent performance across strings of shots. The bull contour provides the stiffness needed for precision work at distance, while the 1-8 twist accommodates a range of 264 bullet weights and styles.

Proof Research's approach goes beyond weight savings. Their carbon barrels are engineered to minimize harmonic vibration and eliminate point-of-impact shift during high-volume shooting sessions—a real advantage when you're zeroing, load testing, or running practice drills. Match-grade accuracy is built in, so your gunsmith can focus on the chamber and threading work knowing the barrel itself will deliver the precision you're after.
