GRT808 Can you post some pictures.
Our revolver has been upgraded with a scuba tank as well. We have the scuba regulator fixed at 120 psi and have a second regulator (standard FRC regulator) that adjusts pressure into the accumulator tank at no more than 60 psi and we have a third regulator that adjusts pressure into a small accumulator tank that operates the modified 3/4 in gate valve we use to fire the contraption.
Our revolver seals are spring loaded pvc on both sides of the revolver cylinder and only open up about 1/8 inch when firing. We get about, never measured it but probably about 100 ft at max elevation. We do have 10 shots though and the accumulator tank refills in less time than it takes to rotate another shot into place.
