Change the pressure gauge is very easy because there is no thread to connect your receiver and the gauge, rotate your gauge anticlockwise by 90 degrees while there is no pressure in your gun. Then you can take it out and change a new one. Don’t forget to check the O-ring on the bottom of the pressure gauge when you change it.
