Lets put it this way - It won't have done your Ion any good. At alli used co2 on ion last month. i didn't know i wasn't supposed to use it. i just bought it and the pball site didnt have any air. i wanted to use it so bad that i ran the marker on co2. i couldn't shoot again after i shot 20pballs? then i waited for 10-15 minutes, it started to shoot again. do you reckon it's damaged or something after i had used co2 few times that day? (i bought the ion on the same day and went straight to a pball site).
i haven't tried firing the ion after that day though. i just read the manual and it said something about anti-syphon tube? do you know where can i get that for my ion? thanks and sorry for asking alot.
