The ATF can barely even define what a gun is. Todays platforms are modular so essentially they choose the largest, non-ware part and put the serial number there. That one part then becomes the "gun". In some cases that part doest even resemble a gun at all.

Will the restriction apply to addative manufacturing as well? will they also limit subtractive manufacturing like CNC? CNC is older, and capable of producing actual high quality firearms. Why not start there?

Are they going to limit highend commercial 3d printers? There exist farms of very high end printers that create parts on demand out of plastic and metal. whats going to happen to their business if parts get randomly flagged as a "gun" because some AI halucinates?

Are they going to ban producing toy guns and props?

Ill stop now, i feel like ive already put more thought into this than the legislators have.
