The PROOF Research BBL CF Blank Bolt .224 Sendero barrel is a precision component engineered for shooters building custom rifles in the 224 Valkyrie, 224 Weatherby Magnum, or other .224-caliber cartridges. This carbon-fiber composite barrel blank delivers the rigidity and thermal stability serious long-range and competition shooters demand, without the weight penalty of all-steel barrels. At 16.5 inches with a 1-7 twist rate, it's configured to stabilize a wide range of .224 projectiles while keeping your overall rifle length manageable for tactical, bench, and field applications.
Built on a proven platform, this barrel features a 2.5-inch breech and 1.20-inch shank diameter—standard dimensions that integrate with most modern rifle actions and components. The Sendero contour strikes a balance between weight savings and rigidity, making it equally at home on a precision range gun or a hunting rifle where every ounce counts. At 2 pounds 8 ounces, the carbon-fiber construction keeps your barrel package light without sacrificing the thermal consistency that precision shooters rely on shot after shot.
This is a blank barrel—you'll need to chamber it, crown it, and fit it to your action—so it's ideal for gunsmiths, experienced builders, or shooters who work with a trusted gunsmith to finalize their build. If you're assembling a custom rifle and want the ballistic platform and weight savings that PROOF Research's carbon-fiber technology delivers, this blank gives you the foundation to do it right.

Yes. This is an unfired, unchambered blank. You'll need to have it chambered, crowned, and fitted to your action by a qualified gunsmith before it's ready to shoot.
The 1.20-inch shank diameter is a standard dimension that works with most modern rifle actions. Confirm compatibility with your action or gunsmith during the build planning phase.
Carbon-fiber barrels reduce overall rifle weight while maintaining the thermal stability and rigidity needed for precision shooting, making them popular for long-range, competition, and hunting builds where weight matters.
