Where can you get a cheap paintball converter from a 12 gram CO2 gun to make it use 9 oz or higher CO2?
call a paintball company and they can custome make one(most companys wil but not all)
If your using 20 gram bullets just switch down to twelve gram bbs. Other wise if its electric or co2 idk. But the best option is buy a new one slower because there pretty cheap. i have 5 spring ones and there fast but not to fast i have a shotgun tro rifles and two pistols. but if you love guns save up your money and buy a paintball gun there awesome
