Custom Carbon Fiber Blank Breakdown:
When it comes to building a precision rifle, every component matters — and the barrel is at the heart of it all. At Preferred Barrel Blanks, we specialize in providing custom carbon fiber blanks that deliver unmatched performance, weight savings, and fast turnaround times. If you're looking for a lightweight, high-performance option for your next rifle build, our carbon fiber barrel blanks are designed to meet the highest standards. Here's why Preferred Barrel Blanks is the go-to choice for premium custom carbon fiber blanks.

Three Carbon Fiber Barrel Blank Options to Match Your Goals
Not all custom carbon fiber blanks are created equal. That’s why we offer three specialized carbon options to match your shooting style and performance needs:
- Classic Carbon: Ideal for those seeking the most weight reduction. Our classic carbon fiber wrap delivers a lightweight barrel while maintaining excellent strength and performance.
- Nickel-Plated Carbon: For shooters who want superior heat dissipation and increased barrel rigidity, our nickel-plated carbon option is the top choice. It’s slightly heavier but delivers outstanding thermal performance.
- 50-50 Nickel/Classic Blend: If you’re looking for a perfect balance between weight savings and enhanced performance, our 50-50 blend offers the best of both worlds.
Each carbon fiber barrel blank option gives you control over your rifle’s final performance characteristics — so you can tailor your build exactly the way you want.
Carbon Fiber Blank Contour Options
We understand that every rifle build is unique, which is why we offer two carbon fiber barrel blank contour styles to fit a wide range of builds and actions. Whether you're seeking a heavier varmint profile or the balance of a Heavy Palma contour, we've got you covered. Both options are crafted to optimize barrel rigidity, accuracy, and balance — ensuring your rifle performs exactly the way you intend, whether at the range or in the field.
The carbon fiber barrel blank contours are based on what shank diameter you need. The Varmint 900 contour has shank sizes of 1”, 1.06”, 1.125”, and 1.150”, with the taper staying consistent down the barrel to the muzzle. The other option is the Heavy Palma, which uses 1.200” and 1.235” breech diameters and features a more dramatic decrease before ending at .900”. The Heavy Palma is a proven competition contour widely recognized by stock makers. In both contour styles, the muzzle finishes at .900” every time.
Lightweight Carbon Blanks Without Sacrificing Strength
Our custom carbon fiber gun barrel blanks are made in-house in the US, using our own precision barrel blanks as the starting point. We carefully wrap and cure each barrel to achieve optimal weight reduction without compromising durability or performance. At 24 inches, depending on bore size, our carbon fiber barrel blanks weigh 3 pounds or less — giving you a significant advantage when carrying your rifle over long distances or when every ounce counts.

Our streamlined production process allows us to deliver your made-to-order carbon fiber barrel blank in just 6–8 weeks.
