In a nutshell, the assault weapons ban did nothing to stop assault weapons from being used. (They are used in less than .02 % of crime so far).
What it said was that:
No weapons can be produced after 1986 that have a combo of three of the following things:
A pistol grip.
A flash Surpressor. (horribly evil)
High Capacity Mag usage.
Bayonet Lug. (if I have the option of bullets....)
Collapsible Stock.
Rifle Grenade Launcher. (where is someone gonna get teh grenade????)
So basically you drop the flash surpressor / rifle grenade launcher, bayonet lug, and the collapsible stock, you have the same old semi-auto weapon...
DOH?! kinda stupid in my eyes! Morons had no clue when they wrote that law, so, you get a law that made no sense.
All the law did was drive up the price on weapons made prior to the ban....
