 That is a powerful weapon. So powerful, it's why you don't use an AR-15 when you're defending your home. It's why, for me, I use a handgun. Shotgun's also good. Don't use your AR-15. It'll go through your wall and hit your neighbor's wall and go into it, and it'll hit somebody in there if somebody's in there possibly. Not good for defense. Very powerful. Much more powerful than a 9mm.
