This turtle half-shell shooter rod for Stern’s Teenage Mutant Ninja Turtles pinball machine shoots great, feels nice and looks awesome! The official Stern shooter rod (katana) is 1/16″ shorter than it is supposed to be which is why everyone has issues plunging with it. This TMNT shooter rod is the proper size and does not require a stronger spring or anything like that! It comes ready to install in your machine.
