The MV50 puts out 2.something CFM, not sure at what psi though. You can run lockers, etc off of them. With the right size tank small air tools in short bursts are possible.
My personal opinion is to set up some on board system over the CO2 tank as it is unlimited supply. I hate having tanks filled.
same here. i was thinking about going with a 5 gallon tank mounted underneath the bed. well see how it goes. info
