I think your eye relief will be screwed up, and if your CMMG is anything like mine, your barrel will be pitted and un-shootable in a few months time (despite your best efforts to clean it after every range session), and you will never be able to reach CMMG on the phone to even begin rectifying the problem.
That ends my rant on CMMG's poor products, and even poorer customer service follow up.
