Pressure regulator for PCP air rifles FX Royale 400 and FX Boss. Thanks to the regulator you will achieve consistent performance and more accurate shooting. This model is compatible with most PCP air rifles with an air cylinder that have the standard M18x1.5 thread.
Installation is very simple; you do not need to make any permanent modifications to your air rifle. First you must release the air and unscrew the cylinder. Then screw the regulator between the cylinder and the rifle body. With the regulator installed, always fill the cylinder via the Quick-Fill on the regulator, never via the quick-fill on the rifle. To fill, you need to purchase a quick coupling separately.
The pressure can be adjusted with a standard screwdriver from 100 to 150 bar. The total range corresponds to roughly 2/3 of a turn. Unscrewing or tightening by more than one full turn can cause the regulation to stop working. To increase the pressure, turn the screw counter-clockwise, and to decrease it, turn it clockwise.
