Also, if they are all illegal, why to stop at 10 rounds if you can make 30? I'm sure the criminal underground will love the new business; there are tens of thousands of metalworkers in the country who have the skill, the machines, the facilities, but have no orders. (Who'd order from them, the Chinese?) They will be listening to the speeches of criminal bosses. If not, the boss will simply buy the shop (not necessarily for a fair price either.) Once the gang has the business up and running, what is to stop them from making locks, stocks and perhaps barrels? All unregistered, full-auto if the customer wants, and for a good price too! You don't even need to design the weapon - there are already lots of excellent designs, ready to be copied! Forget the Prohibition, this is the new goldmine. As the government prohibits manufacturing of new classes of firearms, the citizens will feel more and more need to have some. The crime world will gladly take their coin. That's how it was 90 years ago, and that's how it can be again.
Indeed. Furthermore... if you have the tools and skills, why stop at a firearm when you can make a drone? How'd you like to be a BATF puke making a "house call" out of your armored personnel carrier, and look up and see a couple of THESE bad boys coming at you?
