If they “go wrong” aren’t they just a stock? It’s pretty hard to screw that up. I’m not saying it can’t be done but I believe if I want one I should have one.Bump stocks?
Meh...to me they are more of a curiosity than anything else. I don't see a need nor a practical use for them. They get a hard pass from me.
My hunch is they'd be a hinderance to accuracy and one more layer added to the things that could go wrong.
