Fed.gov (ATF) probably considers anything other than a single-shot to be a machine gun!
And more than one is an “aresenal”.
Oh yes. And if more than two gun owners get together for any reason, then you’re running in a gang.
It reminds me of what my retired-cop cousin once told me: If you hang by yourself in jail, you’re anti-social. If you hang with one other guy, you’re homosexual. If you hang with two or more guys, you’re running in a gang. There’s always a way to negatively label people.

You mean “sling” shot.
