People have been making firearms since the 1600s. Give me lead, sulfur, iron ore, coal or enough trees to make charcoal out of, and I can make a firearm and ammo starting from that.
I really don't need the lead, since the first projectiles were stones.
Since I'm living in the 21st century, my lathe and milling machine in the shop behind the house will work just fine.
It's not rocket science.

Well, between removing the S from Diesel and now, soon, gasoline, there should be no domestic shortage of inexpensive S for the foreseeable future.
If I may make an analogy -- I do not have a lot of artistic skill, but using my simple laserjet printer, I can print a copy of da Vinci's "Mona Lisa". I push the button, and there she is.
With a 3-D printer, any schmuck can push a button have a gun. That's a gamechanger.
True, it isn't but it is difficult to imagine the average citizen having the knowledge and the machinery on hand to carry out such a task.
Aren't you perhaps blowing your own horn just a tiny bit?
