The 1994 Omnibus Crime Bill included a provision that prohibited the manufacture and sale to non-military and police, after September 13, 1994, of semi-automatic rifles equipped with detachable magazines and two or more of the following: bayonet lugs, flash suppressors, protruding pistol grips, folding stocks or threaded muzzles. There are similar guidelines on handguns and shotguns. Additionally, the manufacture and sale to non-military or police of”large-capacity” ammunition magazines (holding more than 10 rounds) were also outlawed. “Assault weapons” and “large” magazines manufactured before September 13, 1994, are exempt from the law.
