Any help would be amazing as a spent a lot of money and I don't have a gun that works
As for the gun, Your LPR needs adjusting. It is far too low to hold the bolt back against the pressure in the shot chamber. I would replace the 2 rear most orings n the bolt kit, the 023 on the back cap screw being the first one since they tend to shear alot, then if it still leaks from the rear i would replace the rearmost 012/013 on the bolt tail. Those are the only 2 oring that can allow for a leak out the rear of the gun
As for the tank, have your local shop replace the burst disc that blew.
