I cannot fill my GAMO Urban with air. The rifle simply will not take air when I attempt to fill it. I am using the same PCP hand pump that I always use to fill the rifle. Has anyone else had this problem and is there a fix for the issue?
If the air just escapes? Then you need to fill the gun with it cocked.
If it's not allowing any air to pass then try and remove the fill port and see if there is a one way valve with a screw? The screw may need to be adjusted.
Sounds like you might have a bit of poop in the fill valve. I would check the probe first and if isn't blocked you will need to disassemble the fill valve. It is fairly basic. Make sure the airtube is totally empty by dry firing, unscrew the valve assembly, disassemble it, clean all the parts and replace any damaged Orings and reassemble.
