Hi guys, i need help please, when i want to reduce the regulator pressure, i remove the front bottle and i should dry fire couple of shots to remove all air inside the chamber, is that right ? Because in my gun i have to dry fire all the way down until pressure reach zero, i am talking about dry firing from lets say 160 bar to 0 which are ALOT of dry fire, is that normal?!?!! Is this the way to reduce the reg pressure on delta wolf ?!! FX impact will release all air from plenum after couple of shots! Why this is happening on Delta Wolf!
