Jimma, the original AWB didn't really ban even one gun. It only stopped domestic production of certain firearms based upon appearance (not function) for the general public. Post-ban semi-auto firearms lost their detachable flash hiders, bayonet lugs and folding stocks but their performance was unchanged. There never was a shortage of high-cap mags available either. It never would have passed without the sunset provision. It caused the Democrats to lose their majorities in both the House and Senate. It had no effect upon crime other than causing The ATF funding raid at Waco and the resulting OKC bombing.
What it did do was make a lot of money for those that had stockpiled pre-ban guns and mags. It also wiped out the senior pro-gun Democrats at that time and left the bottom feeders that are now in control of the Congress.
