Planning on buying my first AI, (a used one most likely) wanting to go with an AXMC, Need some help making a decision on how to proceed........ Wanting to run the 6.5 Crdmr. Primarily, But Hearing conflicting information on whether it’s compatible or not. Does it need the bolt bushed, or do I order a small firing pin bolt? Or be better off just getting a post 14 AX, or AT? If going 6.5? I don’t reload, well not yet anyway. So will be running factory.
