Pressure regulator for Hatsan BT65, Gladius, Galatian II and Flash PCP air rifles.. This device will give you more consistent performance and improved accuracy.
The installation is really simple and straightforward. First you need to drain the air cylinder of any air and unscrew it. Then unscrew the brass cap with valve from the air cylinder and insert the regulator into the air cylinder and screw the brass cap back. All you need to do next is to screw the air cylinder back to the frame of the rifle.
You can still use the Quick-Fill adapter, that comes with your rifle even if you have the regulator installed.
The pressure output can be adjusted with the flat head screwdriver from 100 to 150 bar. The total scale range corresponds to approximately 2/3 turn. Unscrewing, or screwing the setting screw for more than one turn may result in failure of the regulation. To increase the pressure you need to turn the setting screw counterclockwise. To decrease the pressure you must turn it clockwise.
