Does anybody knows how to do maintenance and adjustments for the FWB p700 or p70 main internal air valves? I do not mean the air cylinder but que valve system in the rifle. I saw a photo in the Hicht Hickes Guide but I have no idea how to set the big screw in the bottom of the valve and other possibilities.
The other questions is about de compensator, who has a screw to do some adjustments but I am not sure about doing things with this systems.
Thank you.
