Gents...call Xtreme Guns & Ammo in Richmond Texas. I know they have a 6mm Creedmoor barrel in stock because I had it in my hand a few days ago. It is a Proof Axiom pre fit 26" 7.5" twist Comp contour It is however a Stainless barrel.
They may have some CF Axiom pre fits as well, ask for Vince he's the manager and can hook you up.
