The 1994 AWB was basically a joke. And everyone knew it. ARs and AKs weren't banned. It just meant you couldn't have cosmetic features like folding stocks and flash suppressors on new rifles. During the so-called ban the AR became the most popular rifle in the country. I think it is impossible to ban all AR design rifles because you have to define what an AR is and that just opens the door to making small modifications to the rifle so it no longer meets the definition. The whole purpose of the 1994 cosmetic test was to define an "assault weapon" and we saw how easy it was to get around that so they will be no more successful in any new definition.
