I need to buy a 7mm-08 barrel

The problem is, so few companies make them for AR308's.

The ones I've found are X-caliber, McGowen, and Black Hole Weaponry. I could get a Krieger, but that's way more than I want to spend.

A feller on here just bought an X-Caliber for his 6.5 Swede, thread was titled SS or Carbon or similar. You could ask him if he is satisfied. That's just 1 opinion though. If you wanted, you could call Bison Armory and ask if he'll ream one for you. I know it's a long shot but would only cost you a moment of time. The 6.8 barrel I got from him shoots good.

Mine is a McGowen.
