What do you get when you combine Joerg Sprave of the Slingshot Channel, a drill, some clever woodworking, and four revolver cap guns? Well, in this case, you get a “fully automatic” four-barreled contraption he cheerfully named “Revolverception.”
Seeing how the famed slingshot designer lives in Burgkunstadt, Germany, Sprave elected to use cap guns in place of real working revolvers for his prototype. As he points out, however, the design should also work with any revolver with a trigger pull similar to that of the cap guns. Of course, finding a place where building such a device would be legal can be difficult. Sprave commented that he was unsure if even replacing the cap guns with airsoft guns would be allowed in Germany.
