I recently purchased my first PCP riffle a Hatsan 50 cal. Right out of the box it had 0 BAR in the tank and my compressor wouldn’t fill it up so I got a SCBA tank filled to 300 BAR and tried to fill it with that. All the air leaked out the barrel of the gun and I was unsuccessful in filling it. Anyone know what to do hatsan isn’t responding to my emails and I’m not sure what to do.
