He can try but they would have a hard time doing anything. Unless the government seizes all forms of machinery and hardware (see: dekulakization) they cannot stop people’s ability to make guns if that’s what they feel like they need to do. Also, 3d printed guns are pieces of shit and never used in crimes. It’s more of a proof of concept to demoralize gungrabbers. They need to give up or try and go full internet censorship surveillance state

For example if you are smart you can make a 3d printer. You can get gun plans and printer plans. For now it is totally legal and legitimate to make your own non fully auto guns for yourself. If someone was depraved enough to want to plan some type of violent crime, by the time they were able to make their own gun, they’d probably get a sense of accomplishment and self satisfaction leading them to rethink their plans. Seriously these fuckheads doing school shootings don’t have fathers in the household. They probably couldn’t change the toilet paper roll let alone make a functional weapon.

If you’re concerned about this you should be buying barrels, upper parts kits and ammunition, because those are the important things that may be changed to required to be registered or whatever. If you had a upper parts kit with the bolt, you could probably make the rest out of wood and a trip to ACE if you wanted to, and people can do it legally.

It’s just a shame because the american manufacturing system which led the industrial revolution is totally based on gunsmithing and interchangeable parts. People that are interested in making guns are literally just hobby machinists. And that should be celebrated. It’s a small machine that fits in your hand. Anything else that would be worth making out of metal would be much larger and more expensive
