For a while my jack has been doing this, ever since i switched it from my lancer body to my combat master body, but when i tried using it today it was a lot worse, in the past, when i connected the air, it was like a 70% chance the nozzle would shoot forward and leak a bunch of air, and sometimes when i pressed the trigger it would fix it, other times id have to take the upper off and manually press the nozzle back and it would usually work, when i put the tank into my esg grip today it started shooting fine, except at around 200 fps which is extremely weird considering it always shoots around 300, and when i took the upper off to look at it the nozzle kept leaking, it would shoot a little while still leaking, and im curious if anyone knows what could be wrong? Maybe i need to replace the nozzle or something but im curious since i dont know much about hpa
