Just to solidify the point an AR-15 is not a good home defense weapon. I have two but they would probably be my last choice in a firearm if I heard a door opening at 2 AM. The AR is a good ( not great ) long range weapon, 100 plus yards, and although I'm not a hunter, I am told a capable hunting rifle. I personally prefer a handgun, this is my 28th year as an LEO, and would be hesitant to even grab a long shotgun in close quarter defense, but that would be IMHO better than an AR. A handgun can be drawn close to that body and can clear a room admirably. Burglars do not want confrontation and intimidation factor is something of a liability a jury will convict you of before a poor "defenseless Burglar". Stay with your handgun and get a cheap fun inexpensive to shoot rifle.
