Essentially yes. Most cockers need 300psi, depends how its set up. I'm simply saying a reg that has a clear view of the 300 range attached to an ASA with a plug on the other side. Screw the reg into the ASA then run the macro to another ASA with the tank attached. When you gas it up it will give you the readout of the reg pressure.
