I pit people who refuse to learn from history

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.

According to this article, it is not.

I couldn’t find the original article I read addressing this issue where they noted that the original Liberator didn’t have a rifled barrel either.

The linked site also has an embedded video of the printed Liberator being fired if anyone is interested.

Well then I’ll say it. This gun is incredibly stupid. You could do better with parts straight off the hardware store shelf.

Slippery slope people, WAKE UP…

At first it’s weapons and then…

They will ban the 3d printing of pigeon eggs…:frowning:

People who refuse to learn from history will have to take it again in the summer session, credit/no credit.

I believe another version goes - maybe by Mark Twain:

“History doesn’t repeat itself, but it does harmonize.”

I like it better than the original.
