Christensen Arms 300 Prc 22'' 1-8 Twist Sporter Contour Carbon Fiber Barrel

If you're building or upgrading a precision 300 PRC rifle, a Christensen Arms 300 PRC 22'' carbon fiber barrel brings aerospace-grade engineering to your chamber. This sporter contour barrel pairs a match-grade 416R stainless steel bore with Christensen's proprietary layered carbon fiber construction—a design philosophy borrowed from the aerospace industry that trades heavy steel for lighter weight without sacrificing rigidity or accuracy. The 1-8 twist rate stabilizes 300 PRC loads across the velocity spectrum, making it equally at home on a long-range competition line or in the field chasing big game at distance.

The barrel is manufactured to exacting tolerances (+/- .0001 inch on the bore) and is compatible with Remington 700 actions, a standard that gives you flexibility in your build. Whether you're assembling a custom rifle from scratch or dropping in an upgrade, the sporter contour offers a practical balance—slimmer than a bull barrel for easier handling, stiff enough for the accuracy demands of modern long-range hunting and shooting. The carbon fiber wrap reduces rotating mass and heat signature while keeping overall rifle weight manageable, a real advantage on longer days in the field or at the bench.

Christensen Arms' reputation in precision barrelmaking rests on this kind of attention to detail: aerospace tolerances, quality materials, and a design that works. A 300 PRC barrel of this caliber and twist belongs on a rifle you trust to perform when it matters.

Frequently Asked Questions

Will this barrel work on my Remington 700 action?

Yes. This barrel is manufactured for Remington 700 compatible actions, a standard platform used in many custom rifle builds and aftermarket gunsmithing projects.

What's the advantage of carbon fiber over a traditional steel barrel?

The proprietary layered carbon fiber construction reduces overall barrel weight and manages heat buildup while maintaining the rigidity needed for precision shooting. This makes the rifle lighter and easier to carry without compromising accuracy or durability.

Is the 1-8 twist rate suitable for typical 300 PRC hunting and competition loads?

Yes. The 1-8 twist is engineered to stabilize the range of bullet weights and velocities commonly used in 300 PRC ammunition for both hunting and long-range target shooting.

What does the +/- .0001 bore tolerance mean for accuracy?

This tolerance is exceptionally tight—match-grade precision. It means the bore diameter is held to one ten-thousandth of an inch, ensuring consistent bullet engagement and contributing to the repeatability and accuracy Christensen Arms barrels are known for.
