I'm not sure why anyone needs to buy assault weapons such as the AR-15 (which I believe was once federally banned), and I don't know anyone should be allowed to sell/buy ammunition over the Internet.

Indulge me on the last paragraph please.
Without Googling, tell me what an "assault rifle is" and why should it be banned?
And since I can go buy all the .223 I want at Wal Mart, why should I not get it off the internet?
