    Couldn’t you just, idk. Use a small diameter steel pipe and the rest of it printed? Maybe im missing a whole crapload of physics for that to be sufficient

      Chamber pressures for the 5.56 Nato is 58,000psi. And 9mm is 35,000psi. It takes a pretty good piece of pipe to contain those pressures. Your average seam welded pipe is around 4000 to maybe 10,000 psi.

      Zip guns made from hardware store pipe are just barely good enough to contain a low pressure 12ga bird shot shell.
