I've got 4 Air Arms Alfa Proj PCP pistols. They all have the same issue. After charging them up and firing them they will lose all air pressure, just as though you were pulling back the hammer buttons to release the air intentionally. To be specific, 3 of them lose all air after the first shot. The 4th one will shoot 8-10 times before the same thing happens.
I've disassembled one of them completely (almost) and cleaned and lubricated it. I did not find any apparent damaged or worn out o-rings or other parts but I'm no expert. After reassembly there was no change.
Any help would be appreciated.
Thanks.
