As far as i know there has never been an Ion made with only one firing mode?my mate has an ion and his only has one firing mode which is semi
on the other hand, when i bought mine it had two modes, semi and ramping. and im pretty sure it was a stock board.
to change the modes you have to take the grips off the marker and on the board underneath theres a button(s) you can change the settings with (including changing the firing mode), im not quite sure how though.
Wrong, check the link above.the UK board only has semi and the US board has semi, ramping and fully auto.
