This is Proof Research's Competition line — a match-grade stainless steel barrel blank rather than a carbon-wrapped one, for builders who want the mass and harmonics of a traditional steel competition barrel. It's a .224 caliber blank, 26 inches, with a 1:8 twist, which is the versatile choice across most modern heavy .224 bullets used for long-range and PRS-style shooting. Like all blanks, it ships unchambered and unthreaded for a qualified gunsmith to finish to your action, cartridge and contour. Proof's rifling, lapping and inspection process is the same one behind its carbon-wrapped barrels.
