Gun owner here.
AR15 is a range gun for most people. Somewhat useful for home defense. I'd rather grab the .380 with hollow points. If I miss, it's stopping in the wall.
AR15 is really only useful for dropping coyotes. Not really enough power for deer hunting at any longer distance. Waste of power for smaller animals. Too much meat damage.
For hunting, I'll take a scoped bolt action and my 12ga with a couple of chokes. Plus a .22 or 410 for squirrels and rabbits.
With that, the gun enthusiast talking points don't really hold water with me regarding the AR semis. They're militia weapons. Guess that's why the hardcore 2A supporters want to keep them legal.
