A Proof Research 264 Cal 24" Sendero Contour Carbon Fiber Wrapped Bolt Action Barrel Blank gives your build a significant weight advantage without sacrificing the rigidity and accuracy you need for precision rifle work. This barrel blank arrives unthreaded and unchambered, ready for your gunsmith to finish according to your exact specifications. The 1:7.50" twist rate and 4-groove configuration are optimized for the .264 caliber cartridge, and the Sendero contour profile balances strength with the weight savings that carbon fiber construction delivers.
Proof Research's carbon fiber wrap technology achieves up to 64% weight reduction versus traditional steel barrels while maintaining stiffness and durability. The carbon fiber envelope resists cosmetic damage—nicks, dings, and weather-related wear—better than bare steel, which means less maintenance concern on hard-use hunts or field operations. You'll also benefit from improved heat dissipation characteristics, allowing the barrel to run cooler during extended shooting sessions and reducing the likelihood of point-of-impact shift during high-volume fire. The reduced harmonic vibration inherent to carbon-wrapped construction contributes to consistent accuracy across shooting strings.
Whether you're building a long-range hunting rifle, a precision target gun, or an overlanding rifle where every ounce matters, this barrel blank lets you work with a gunsmith to create a custom rifle tailored to your caliber preferences and chamber specifications. Proof Research's reputation for match-grade accuracy and engineering rigor makes this a serious choice for shooters who won't compromise on either performance or weight.
| Caliber | .264 Cal |
| Barrel Length | 24" |
| Contour | Sendero |
| Twist Rate | 1:7.50" |
| Rifling Grooves | 4 |
| Construction | Carbon Fiber Wrapped |
| Bolt Action Blank | Unthreaded and Unchambered |
This blank is designed for bolt-action rifles in .264 caliber. Your gunsmith will thread it to match your specific action and chamber it to your chosen .264 specifications, so compatibility depends on your action and how your gunsmith finishes the blank. Confirm with your smith before ordering.
A barrel blank arrives without threads on the breech end and without a chamber reamed. Your gunsmith will handle both the threading and chambering to match your rifle's action and your preferred .264 cartridge variant (such as .264 Winchester Magnum or .264 Creedmoor).
Proof Research's carbon fiber wrap construction achieves up to 64% weight reduction versus traditional steel barrels of similar contour and length. The exact weight savings will depend on your gunsmith's final configuration, but carbon fiber construction consistently delivers significant weight savings for precision rifle builds.
Yes. The carbon fiber wrap is resistant to cosmetic damage like nicks and dings, and it resists weather-related degradation better than bare steel. This makes it well-suited to hard hunting and field use where traditional barrels might show wear more readily.
