The AR in 5.56 does a lot, for sure. And I don't even currently own a bolt gun and won't if I can't get one to match my specs.
For me, it would be an inexpensive way to get into a bigger caliber for hunting and other purposes, and something I can leave in the car (minus optic, hence my iron sight requirement) that wouldn't impact me financially and which would make me morally feel a little less bad (letting a bolt-action into the hands of a turd rather than an evil baby killing AR).
I *don't* need or want a precision bolt action. AR would do just as good IMO. I *don't* want a $4k+ Brockman custom (well, I do, but not enough to spend). At that cost I'd just take the AR.
