Well i have a team member who has all of the Systema PTW cylinders and i'd installed each one of them and m90 black, m110 blue, m130 gold, run just fine but the m150 red cylinder runs just fine but its not feeding into the hopup unit.
I even switched multi able Celcius an Systema mags and still not luck and has anyone been having this same issue.
