Wait until someone comes out with a 3D Gatling gun! Watch lib and ATF heads spin like that’s cent in “the exorcist”. Then you’ll see the nazis come out in force...with predictable results.

Actually, at the Federal level, gatling guns made pre 1900 design are legal to make. There are lots of plans out there for machinists.

Cannons are also legal. I've got an uncle that used to build them. He was part of a club that built them and shot them a couple of times a year.
