The lower receiver of an AR15 is legally considered the firearm. You can buy all other parts straight up, but you have to go through federal background checks on that one. Even with private sales, at least the first buyer would have to have gone through the process.
On its own, it’s just a chunk of plastic or metal. It’s not pressure bearing and isn’t even all that mechanically stressed in typical use. Therefore, you can print that one part off, buy all other parts, bypass all checks, and have a completely unregistered AR15.
In the UK, regulation tends to be around pressure bearing parts, and this is a lot more sensible.

While I majorly disagree with this legislation, its not about plastic guns.
They only regulate the part of a gun that has the serial number, not the other parts. For “repairability.” Guess what that one part is easily made of? Yup, plastic.
People are printing the easy part, and buying all the rest in metal. Proper control would be to regulate the sale of commercially manufactured replacement parts, not a tool.

Maybe start regulating normal guns more first… 3D printed guns are not a problem anywhere in the world.

Well, yes, but I was specifically going down the replacement part road because the intent of the legislation is to limit ghost guns (unregistered firearms), not guns overall. IMO it’s just a play to say “we are cracking down on guns!” without actually doing it. And since it only hurts a niche audience, who cares, right?

So the point isn’t 3d printers making guns, it’s 3d printers enabling people to escape registration of guns, especially for unregulated sale of guns.
