Agree with Bible Belt and Zekko. For home defense you want something for close quarters. An assault rifle is overkill and will not only go through the target but three or four walls as well.
If you want a close quarters rifle go with something like this. It's similar to the MP5 that a lot of special forces and swat teams use for close quarter combat but a fraction of the price.

You'll get a rifle but with hand gun rounds which will be hollow point so they won't go through 3 walls. You want to kill the target not the little old lady who lives next door. Or you could just go with a shotgun. For handgun, there are too many to list. Do you want a wheel gun (.357) or a semi auto (Glock etc)? Keep it simple and use what feels right for you. Or just by one of everything
