LOL. This shows how ignorant Carlson is about firearms. The reason AR-15s are not generally used to hunt or kill deer is that they are not powerful enough to do so humanely. The rifles used to "hunt or kill deer" by millions of hunters are MUCH more powerful and deadly than an AR-15. Usually either a .30 caliber rifle or a .12 gauge shotgun loaded with slugs - I'd rather be shot at by an AR-15 than either of those.

Spoken like a true sportsman. I commend you for your insight, as that’s what those of us who respect our quarry feel.
