They demonstrably do, multiple of them, and none of them used 3D printed weapons.

So there are people who would have a use for a high powered rifle with limited durability.

> What I'm saying is that no one is going to build a lower in this manner for a firearm chambered in 7.62 and do anything useful/important with it. Maybe the cartridge size here is a distraction, idk, but this isn't a specification that I would consider common and/or useful for 3D printing a firearm.

The fact that no one was caught using such a weapon is irrelevant. You stated that there are people out there who would use it, so your statement that "no one" would want to is untrue.

Huh? There is no evidence that anyone is using a 3D printed 7.62 weapon system to do crimes. Of the existing evidence, criminals overwhelmingly use conventional firearms. I'm not understanding your point. The would-be and successful assassins in the news the last couple years used standard rifles, ranging from 5.56 to .03-06 in caliber. I think you are assuming that criminals are less sensitive to equipment reliability than they actually are.

Let me put it this way. If 3D printed firearms were such a game changer, they would already be using them at scale. They are not, and these laws are part of a fundamental misunderstanding about how firearms function and how 3D printing technology works.

You are arguing against a point I am not defending. I am giving a retort against your statement that you can't imagine why anyone would want a high powered rifle that had a limited reliability window. You admitted that there was a use case for it, and I called that out. That's it. I am not defending nor opposing the ability to 3D print firearms.

		I don't think I actually did admit that, and I think the confusion lies in your assumption that someone who wants to do a crime is willing to accept the reliability issues. Perhaps it's worth pointing out that these reliability issues aren't simply lower n-cycles before failure. The weapon could explode on you on the first shot. The probability of this happening is lower for the less powerful cartridges (as I implied earlier but perhaps should've been more explicit). This concept of a "reliability window" is not the right way to think about this. In other words, if someone handed me a 3D printed 7.62 weapon system I would refuse to fire it, and call the person who made it an idiot.
