All timmy are good on air, a 45/45 filled to 4K i would say around 6-8pods and a hopper. I run a 48/45 and get like 6 plus hopper on a 3.5K i think w/ a protege or g6r, thats w/ a slp reg.
Either find a pressure tester for it or make one from macro, i use a macro one. The real one would be easier since its screws in but macro rig works. Test your gun at the BEGINNING of every day of play, ifs LPRs not at 70 put it to 70 or 60-65 with LP poppet.
Buy a oringmonkey kit for it, makes life easyer. Buy dow55 from macrolineguy.com for $5 a oz. Maintenance is easy and the manual covers when and how to take care of everything, very simple.
Set LPR to 70psi, adjust HPR to field velocity. Shoot people
