4 Mode Button Controller Mod Kit 

4 Mode Button Kit

What sets this mod kit apart from the rest is the fact that you can use "mod buttons" to control the mode you are in as well as turn the left or the right trigger on or off. This allows for quick switching of modes and it also lets you turn the rapidfire off quickly for either trigger. To switch modes, you need to hold the mod button for either trigger for 3 seconds. This kit requires drilling two holes into the back of your controller.
