Unturned Barrel Blanks | Precision Drilled, Reamed & Button Rifled

At Preferred Barrel Blanks, quality starts with the foundation of every great barrel. Our unturned barrel blanks are manufactured using precision drilling, reaming, and button rifling processes designed to deliver consistent bore dimensions, uniform rifling, and a high-quality foundation for custom barrel manufacturing.

Using quality materials, precision tooling, and specialized manufacturing equipment, we produce unturned, non-contoured barrel blanks for gunsmiths, custom barrel makers, and manufacturers who want the flexibility to create a barrel tailored to their specific project.

Precision Manufacturing from the Inside Out

Precision Drilling: Every barrel blank begins with a carefully drilled bore. Precision drilling establishes the foundation for the subsequent machining operations, helping create the consistent internal geometry required for quality barrel manufacturing.

Precision Reaming: After drilling, the bore is reamed to refine its internal surface and dimensions. This critical step prepares the bore for button rifling and helps establish the uniformity needed throughout the manufacturing process.

Button Rifling: Our button-rifling process forms the rifling inside the bore using specialized tooling. This process creates the lands and grooves that define the barrel’s rifling profile. With a variety of available calibers and twist rates, you can select specifications suited to your intended barrel design.

Every step contributes to the quality of the finished bore and provides a solid starting point for further machining and customization.

Customize Your Barrel Blank to Fit Your Project

No two custom barrel projects are exactly alike. Preferred Barrel Blanks offers a variety of configurable options to help you find the right starting point for your application.

• Caliber Selection: Choose from a broad range of available calibers, from small-bore options to larger rifle and specialty calibers.
• Twist Rate Options: Select from available twist rates to match your intended barrel specifications.
• Blank Lengths: Choose an available length to accommodate your planned machining and finished barrel dimensions.
• Steel Options: Select from the available material options for your project.
• Optional Bore Lapping: Add our barrel-lapping service to further refine the bore and rifling surface.

Our standard unturned barrel blanks have a 1.250-inch outside diameter, with other material sizes available for specific requirements. Because these blanks are supplied without a finished external contour, they provide flexibility for subsequent machining to your desired barrel profile.
