Anyway i wated to shoot it so i hooked up my 20oz co2(with out antisiphon) and It would shot onwe shot and than wuldent recock. So i refilled my tank right after that it was fine. I was shooting pretty fast and nothing was wrong except one ball broke. That and the bottom line got really cold and sweaty. Also what is the worst thing liquid co2 can do to the reg.
