I've been saying that every state that passes a law pertaining to firearms should include that in the bill. If full autos and suppressors, including all other accessories like AP, tracer and incendiary ammo, AND M203 launchers aren't included in the bill, then it's basically useless. If they want to use the "old laws" argument about the Second Amendment, then we'll use the old laws argument about rapid-fire printing presses, telephones, satellite communication and the internet, and they'll all have to go away.
The bills I read all seem to specifically deem machineguns illegal.
Personally, I don't see anything wrong with people owning grenades, mortars, claymores, machineguns..... etc.
While that indeed should be the case, understand that on the scale of things the feds get wound up about, post-’86 full-auto is very close to the top of the list. While some states are looking for a fight over sovereignty, they don’t want it to be _that_ fight.
