only the non critical to function parts can be plastic
This just isn’t reality. For .22lr, nearly 100% of the gun can be plastic, including the barrel. Here are two real examples where the only required metal component is the firing pin:

3dprint.com/…/worlds-1st-3d-printed-revolver/
For more reliable and more powerful guns, some critical components must be metal, of course, like the barrel might at least require a liner, but the majority of the gun and internal mechanism can still be plastic, not only non-functional or cosmetic parts.
And you can use literally anything else other than 3D printed stuff. So why is 3D printed even an issue.
Idk, I didn’t say it is. I’m just informing you that 3D printed guns are real, not a “fallacy”, some function very well and reliably, and can actually be made with almost no or minimal metal parts

In the United States, only the lower is considered a gun. There’s no check needed to buy the barrel or slide components.

You kidding? I know nothing about these things but that sounds just wrong.

Nope, not kidding. the receiver is the component that is registered as a firearm, and the rest of the parts that go in it are unregulated. That’s also why you may have heard of “80%” receivers. They’re not machined all of the way so they are not considered firearms and the purchaser can then finish the machining and install the parts.
