Help required please. I recently received a Scorpion P12 with factory fitted regulator which suddenly dumped the cylinder after a shot. Pressure was still ~100 bar at the time.
It was impossible to refill in spite of it being cocked with air leaking past the valve into the barrel.
A quick easy disassembly showed a partially unscrewed brass "nozzle" on the front end of the regulator, loose and freely rotating by hand.
This I screwed in hand tight.
Refilled to 100 bar and viola, no gas leak
BUT The valve is now not opening on the hammer release and I am sitting with a 100 bar pressurized cylinder unable to empty it!
Any ideas on the way forward?
