Saw, handled and shot one at the Flatwater shoot in Nebraska years ago. A guy named Bob Egbert owned it. I remember it going bang every time, but it sure was a Rube Goldberg of a gun. I remember being amazed by it, but I think that was more of the novelty regarding the gun & it’s design than anything else. When you have one in your hands….the thought will cross your mind “Wtf were they thinking?, or simply “Why?”.
They’re cool, in a Data from Goonies kinda way.
