Pressure regulator for Hatsan AT44 and Bullboss helps stabilize the performance of the rifle. It is supplied including a seal, which is used due to the poor internal surface of some air cylinders.
The regulator is installed quite easily. You just need to have the air released from the cylinder, unscrew it from the rifle body, unscrew the cylinder valve, slide the regulator inside and screw the valve directly into the regulator. Then simply screw the cylinder back onto the rifle body. The way of filling air does not change after installing the regulator. You can continue to use the existing Quick Fill valve supplied with the rifle.
Adjusting the air pressure is very easy. The groove in the red semicircle serves both as a screw and as an indicator of the value between 100 and 150 bar. You just turn the screw with a screwdriver to the desired position. Adjustment is carried out only on a regulator that is not mounted.
