Not to mention all the shotguns in America that *could be* sawed off.
It' a little more complicated than that. Their regulations (not the law, just their regulations) define any gun, which means any receiver, that was once a machine gun as a machine gun. That's the main reason all, well most the Navy still uses theirs, the M-14s haven't been distributed through the Civilian Marksmanship Program. They are select fire, and even with the select fire parts removed, even if "removed" means ground off the receiver, BATFE considers them to be machine guns, which the subjects are not allowed to possess. There is some RUMINT going aroudn that CMP and BATFE have come to some sort of agreement on that would allow the M-14s to have their recievers modified so that without welding and machine work, they could not be converted back to select fire, and thus sold through CMP. If so, and I stress it's RUMINT, I want one. All the CETMEs, FN/FALs, G-3s and any other "battle rifles" that have been imported must be fitted with a new receiver before the rest of the parts (a kit) can be assembled into a functioning semi-auto firearm. Even then they have to use a certain number of US made parts beside the reciever, due to the Bush I non-sporting purpose import ban and the subsequent codifying into law of the gist of that ban.
