this will allow you to shoot twice with only one trigger pull
take apart the controller diagram above
now solder a wire on to each of the center prongs kind of like you would do for a quickscope mod then connect a momentary switch.
note that all of these wires are not required just the ones on the button that goes under the trigger
now put the switch behind the right trigger so that when you pull it the button gets pressed this may require cutting and trimming aslo i super glued the button in place so that it would not move around then put the controller back together this now allows you to shoot twice for every trigger pull once when you push the trigger down and again when you let off of the trigger. so there you go rate, comment, share, and subscibe. this will really help me.
