I'm not worried. Firearms and replacement parts will always be available. After all, did Prohibition stop us from drinking? Has the war on drugs prevented anyone from getting their poison of choice on nearly every street corner? Have laws in gun-free Mexico stopped cartels from arming up with the latest military hardware, to include fully automatic weapons? The government can pass all the laws they want, and it's apparent that unconstitutionality isn't a consideration, but in the end the black market will fill the void created by shutting down America's civilian firearms industry.

I saw a video of an illegal firearms factory in either Pakistan or China. Small foundry, lathe, milling machine.

The sort of thing you could do in a garage.
