I got to tell you, and we use them in the military, I would rather have something with a bit more power to it. In our version we're shooting an amped up .22 IMO. Not being an expert myself.
They're not the end-all-be-all, but I like them. I think they're more fun to shoot than anything. I'm sure they're powerful enough to take out some zombie brains though. :P I don't hunt, but I'm sure a bolt action 270 or 30-06 would be the way to go for that. I know people do hunt with ARs, I just don't know how it stacks against the competition.
