I would rather use a little loctite (which I have never had to), then make custom shims for my rifle.In all seriousnes I still like the ACR, but will wait a bit before the bugs are out, just like the XCR's.
Keep in-mind that the few affected rifles would have in all likelihood been remedied by now had they not essentially been sitting for the better part of a year pending an FRT...
To each their own, but I've at least put both in my hands before making a determination on preference (I prefer the ACR). And yes, the ACR is more money; but I'd wager that when a NR 6.8SPC kit becomes available the ACR will be a pretty hot item.
