The aerospace-grade carbon fiber used has a specific strength up to 30 times greater than the strength of stainless steel and a specific stiffness up to 7 times greater than steel. This carbon fiber wrapped stainless steel is up to 64% lighter than traditional steel barrels of similar contour. The helical wrapping pattern allows the carbon fibers to efficiently dissipate heat emanating from the barrel rather than insulating it. This means that the barrels will stay cooler and last longer.

This Proof Research Action Bolt Barrel have been designed for safe operation with most known cartridges and within SAAMI and CIP pressure limits. The whole manufacturing process of these barrels have been patented by Proof Research.
By combining PRÕs unique manufacturing process with their advanced technology, they have managed to produce rifle barrels that are durable, lightweight, heat resistance and overall provide superior performance. There is no need to look further for a better barrel.
