I have developed a fire mode changer for the Ion paintball gun. The fire mode changer will allow you to change the fire mode setting of your Ion paintball marker without opening the grips first. Imagine playing a scenario game the real way. As far as I know this is the only fire mode changer available for the Ion stock board.
