I am almost done with my rifle. I will be doing final touch-up and LED's this weekend. I had an idea though and wondered if anyone has tried this or could dispell the thought. I have a couple of Playstation 2 joysticks laying around with the "rumble" feature. For those who don't know, the joystick/controller literally shakes in your hand during certain on-screen actions. Does anyone know how or think it would be worth the effort taking the controller apart and putting the mechanism in my rifle. When the trigger is pressed or a switch is thrown, the rifle would shake, emulating actual gun fire. Make fun if you must. I know I would. I am just looking for some incredible realism. TIA.
