co2 and the level 10 mod will work fine.... how ever you had runnin co2 before will work fine with the LvX......
myself this is the reason i kept my mag valve when i got my retro.... for those odd dayz when there is no hpa availible.... like when the compresser at my local field died this summer... both valves have the LvX even if they didnt... it only takes a couple of min to switch it over......
