Well if you want a non-sarcastic answer and are willing to listen here I'll explain how the laws work here.
There are only 7 states that prohibit
semi-automatic variants of the AK-47 (and other semi-automatics M4, SKS, Uzi etc...) California, Connecticut, New Jersey, Hawaii and Massachusetts. Some states don't ban them out right but may have local bans in certain areas of the state i.e. New York and Illinois.
In every other state
semi-autos (M4's, AK's, SKS's, Uzi's etc...) are 100% legal and can be purchased like any other rifle, handgun or shotgun at a regular gun store. My state being one of them.
Full autos, while not outright "illegal" can still be
obtained legally, there is a lot of red tape tho and most people don't bother. You have to get a stamp from the ATF, pay a $200 fee, find a Class 3 (Full auto) dealer, then buy the gun which has to be made pre-1984 (and they aren't cheap anymore). Class 3 dealers (items) also include sawed off shotguns (under 18'), grenades, silencers and other military equipment.
Once you do all that then you have to have your local sheriff sign off on it, and a lot more states have laws in place that prohibit FULL AUTO and Class 3 items and/or local law does not have to allow possession. In full contrast to laws regarding semi-auto which are NOT Class 3.
I think that there is a lot of confusion over what is full auto and semi-auto. What I own are all semi-auto... just because it's an AK, doesn't automatically mean it's full-auto, because its not... come on man I thought you knew all about guns
