Before you thrust your opinion in our face, howzabout you learn what you're talking about?
* Bumpfire refers to the WAY A GUN IS FIRED - it does NOT refer to the kind of gun that one is talking about
* Because of the amount of travel a trigger takes to make the hammer drop, bump firing occurs in auto rifles and auto pistols, but NOT revolvers!
* And while I bask in your ignorance, shoulder stocks and long barrels have nothing to do with bump firing, regardless of what gun they're on! Do yourself a favor and watch this YouTube demonstration of bump fire:
