Not only that, but the definition of "assault weapon" is arbitrary and based on physical appearance. Under the prior "ban" it was illegal to sell a semi-automatic, magazine-fed, center-fire rifle which had two or more of a meaningless set of military-looking features.
The features included such nonsense as a pistol-grip, a flash-suppressor, or a bayonet lug (not even a bayonet but the little piece of metal which allowed one to be attached).
Prior to the enactment of Kalifornia's equally ridiculous laws, I purchased a rifle which was completely legal to manufacture, transfer, and possess DURING the ban.
When Kalifornia passed its ridiculous laws, I found it necessary to remove the pistol-grip in order to keep from having to register it as if it were a nuclear weapon.
The truth of the matter, which anti-gunners can't stand, is that ALL weapons are lethal and can be used to carry out a murderous attack, as well as being used to stop such an attack.
Nothing short of outlawing ALL weapons will ever satisfy the anti-gunners. And even then they will ignorantly claim surprise that guns will still be as available as marijuana, meth, or crack. Liberals are simply stupid people who act on their feelings and who are unable to understand the difference between "cause" and "effect".
