Looked into the ones you mentioned, both require non-printed parts.
Those are better than what I had seen, but aren't even on the same scale as what someone can make with a mil or a lathe casually in a couple days
Of course they do, but the serialized part that is run through NICs is printable, the rest you can order online or get at home depot.
Of course plastic, extruded or otherwise, is less strong than metal. That wasn't the question. You can get a good few thousand rounds out of those before they crack and when they do, they crack along a layer and are not "more dangerous for the user" by any stretch of the imagination.
