Walther LG300 Dominator 12 ft# air cylinder

[PatrickB]

Hello,
Question, am I in the right board for what I am looking for (after you read it)?

So I have the above LG300 and everyone knows you have to unscrew them to fill them up. I am asking the brain trust here if they could come up with a quick fill system like Air Arms etc... to replace the pressure gauge on. the tank and make the top quick fill? There was a fellow from Check republic who was making this for a while but he has since disappeared from the boards.I mean Styer, Anschutz, FWB, and Walther none of them have a quick fill for their cylinders. These people are still stuck in the dark ages.
Ok thanks,
Pat

I have had Mac1 replace the gauge for a foster fitting on a FWB P70 and an AA S400 MPR.
