An overly sawed-off shotgun:
A hand-held M2 .50-caliber machine gun:
A hand-held 7.62 mm minigun:
Note that neither of those machine guns is anywhere near on-target after about a tenth of a second of firing.
Basically… all kinda useless. And I’m glad I live in a country where people can make and fire such things.
And because why not… here’s a kludged six-barreled shotgun. There are some ergonomics issues.
