Madbull c02 charger gauge reading issue

[Strelok]

Hey there. I've had a madbull c02 charger for a number of years now, just pulled it out of the storage box and stuck some c02 in it.

I've forgotten how to use it since I got it, and i'm unsure whether my charger is broken or not.

I can inject c02 into my 40mm shells, but i'm getting a constant reading of 800 psi no matter how I adjust the knob on the side of the charger. I'm assuming tightening the knob will reduce the psi, but i'm not seeing any difference in the reading when I do so.

If anyone has a better idea of how to use these things, let me know. thanks!

Loosening the knob drops the pressure. Remove the knob and try to fill something to remove the built up co2 inside the charger. If the gauge is still frozen, you'll have to replace it. Airsoft Parts Canada might be able to get you a replacement or you could try an air valve & fitting store to see if they have gauges small enough.

Alright, thanks! I'll see how it reads when I'm home in a couple hours.
