FX IMPACT M3 not filling with air

[MattHamilton]

Has anyone experienced their M3 not filling with air. My dive tank is full (300Bar). I connect it to the gun and no air is going into the gun or the bottle. I’ve never seen this before. I’ve tested the dive bottle on another rifle and it’s filling fine. Any suggestions would be greatly appreciated

First thing is to check that the foster is properly connected to the bottle. These can be Finicky with their location. Once it’s clipped in, wiggle it to see if it’s actually connected or not. If that’s ok, I would say somethings wrong with the check valve in the foster fitting, the first reg is not allowing air into the bottle, or the bottle isn’t properly screwed on.

Thanks mate. It was the valve pin that sits in the actual foster fitting, it had some dirt in it and wasn’t opening up properly. I polished it up and it’s working perfectly now
