Looking for an inline regulator to teather my bigbore to my Drager SCBA tank. I have a fill station and can fill the rifle. But with getting 2 or 3 shots per fill. It is a lot of messing around. Plus I want the same pressure for each shot. I can teather my Marauder to my AV tank because it has a built in regulator in the tank’s valve. I have looked at Joe B’s regulator. While it would be perfect, the price is out of my reach. I looked at Stickman too. While it would make a good fill station and has cascade capabilities, it doesn’t have the variable regulator I am after. Thanks Darrell
