Christensen Arms 308 Caliber 26'' 1-10 Twist Target Contour Carbon Fiber Blank

If you're a custom rifle builder or gunsmith looking to craft a precision .308 rifle, the Christensen Arms 308 Caliber 26" 1-10 Twist Target Contour Carbon Fiber Blank gives you a match-grade foundation without the weight penalty of traditional steel. This is a gunsmith blank—the starting material for a complete custom build—engineered with Christensen's proprietary carbon fiber layering system wrapped around a 416R stainless steel bore. You get the strength and accuracy potential of premium barrel steel with a finished weight significantly lighter than a comparable steel barrel, making it ideal for hunters and target shooters who value reduced recoil and easier handling without sacrificing precision.

The bore itself is precision-engineered to tight tolerances: match-grade 416R stainless, measured to ±.0001", then bored, reamed, hand-lapped, and button rifled. The 1-10 twist rate and target contour are set, so you're building on a solid, repeatable platform. The barrel comes with a threaded muzzle and thread protector, ready for you or a qualified gunsmith to chamber and finish according to your build specs. This is where quality starts—before any chambering, crowning, or final fitting work.

Chambering finishing should only be performed by a qualified gunsmith, so plan your build accordingly. The estimated weight of the blank (unfitted) falls between 2 lbs 12 oz and 3 lbs 5 oz, though final weight depends on how your gunsmith finishes the chamber and muzzle threads. This is a component for builders who understand rifle assembly; if you're assembling a custom .308, you're getting a barrel blank with the precision and lightweight advantage that Christensen Arms is known for.

Frequently Asked Questions

Can I use this barrel blank as-is, or do I need a gunsmith?

This is a barrel blank—a gunsmithing component. Chamber finishing must be done by a qualified gunsmith. You cannot fire this barrel until it is properly chambered and fitted to a rifle action.

What twist rate is this barrel, and what bullets will it stabilize?

This blank has a 1-10 twist rate, which is a common .308 rate suitable for a broad range of .308 projectiles from lighter to heavier bullets. Your gunsmith can advise on the specific bullet weights your final rifle will handle best.

How much lighter is this than a steel barrel?

The carbon fiber construction weighs significantly less than a steel barrel of the same target contour. The estimated blank weight is between 2 lbs 12 oz and 3 lbs 5 oz, but final weight depends on how your gunsmith finishes the chamber and muzzle threads.
