It's not a .308 barrel, but I recently installed an x-caliber barrel chambered in 6.5 CM, and was extremely happy with the accuracy. Price is in the ball park of the ranier also. I did buy a bolt at the same time, and had it headspaced to that barrel.
They had been recommended to me by a local gun shop that specializes in comp guns, and I'll have to say I was not disappointed.
