Can anyone (in a state where it's legal) own a class III automatic weapon? My understanding is that a person has to pay a $200 tax, get a local sheriff to sign off on it, and file some paperwork to legally own one. is this right? I know i'll probably never be able to afford a nice automatic weapon like an MP5 or M-4($15,000+), but i'd still like to know if it's possible. Maybe i'll win the lottery.
