I have a little used BARracuda ( Daystate ) and I used it on Sunday at Shelford Gun Club ( charged it up about 4 times before, thats all ) . Its lovely to use and with the Weirauch silencer , very quiet.. I used it until pressure was obviously falling and then used another gun until I went home..
Tonight I put a better scope on the BARracuda with the idea of sighting in at Shelford tomorrow but I find that the gun will not hold its charge of air. I can tell that it is filling , but when I release the bleed valve all the air is expelled
leaving the gun empty . Part of the metalwork is warm , althouth the exit areas are increasingly cold due to refrigerative effects.I am guessing that a non return valve is malfunctioning..Does anyone have any experience / advice about this please ?

Will it need to go back to Daystate ?
