Proof Research Carbon Fiber Bolt Action Barrel - 101025:

Because Proof rifle barrels are engineered for thermal performance, they also move heat very effectively through the wall of the barrel, greatly increasing heat transport and resulting in barrels that cool faster and maintain accuracy over repeated fire.

The end result is an aerospace-grade, high-fiber content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and maintains its accuracy in the most demanding environments.

The aerospace-grade carbon fiber Proof uses has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fiber barrel. The Proof helical wrapping pattern favors the longitudinal thermal diffusivity of the carbon fibers (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel rather than insulating it.

Advantages of Carbon Fiber-Wrapped Rifle Barrels

• Up to 64% lighter than traditional steel barrels of similar contour
• Match-grade accuracy
• Improved heat dissipation for cooler and longer lasting barrels
• No point-of-impact shift during high-volume fire
• Reduced harmonic barrel vibration
• Unprecedented durability
