It makes a difference to distinquish the printed gun from a zip gun. And I’m interested if this actually worked because I can’t see the plastics used in printers making effective rifling. If they are rifled, and the rifling works, the guns are quite a bit different from a zip gun. I doubt they are rifled because I think the first shot would destroy the rifling, and if it doesn’t jam and blow on the first bullet it certainly would on the second.
But I’d like to know before I argue that the plastic barrel is a stupid idea because the barrel could be made out of a piece of steel pipe and not be destroyed by firing the gun.
No, actually, such laws are really spectacularly unsuccessful, in and of themselves. I take it that you’re unfamiliar with all of the methods used to try to prevent counterfeiting of money?
I was attempting a bit of ironic humor, that’s why I mentioned the 100K downloads and the DoD shutting it down as a done deal. Of course the genie is out of the bottle, DoD or not.
