Proof Research pioneered the carbon-fiber-wrapped barrel, and the company's barrels are the reason a lot of hunters are willing to spend real money on weight savings. A carbon-wrapped barrel holds the stiffness of a heavy contour while cutting significant weight, and it sheds heat differently than steel alone, which helps keep groups consistent over a string.

This is a pre-fit barrel cut for the Sig Cross in 25 Creedmoor at 20 inches, headspaced and shouldered to drop into the host action with basic tools rather than a full gunsmithing job.
