Cue Alanis Morrisette. That was the one thing United States vs Miller did rule.
Well, the distinction between "civilian" and "military" weapons is just a bunch of argle-bargle and a barrel of red herrings, anyway.
The only real point in dispute is the equity point, viz., that liberals demand a monopoly of force located in their own hands. Period. They need to go eff themselves, "forcefully".
And btw, Miller needs to be taken down as a juridical bagatelle, a constitutional and procedural horror show engineered, like so many other things, by Franklin Roosevelt, who was no friend either of the Constitution or of the People.
