re: Do I need a permit or anything to buy an AR-15

My $.02: I find it a little concerning that a guy who has only fired a handgun a few years back (or however he put it) wants to get into guns by buying an AR. I guarantee he is choosing this weapon because he thinks it looks cool or because he thinks it will make him look cool. I don't think that is a healthy or sustainable reason to get into firearms. It is NOT a good choice for home defense, especially for a beginner. Also, the thought of someone learning to shoot a rifle with a loaded 30 round mag should be concerning to anyone at the range that day. You know he won't just put a couple of rounds in the mag the first time.

If he is not going to be hunting, a handgun or shotgun is probably a better choice to start.
