Air Arms Owners Club

Wonder why or Air Arms dont fit the filling gauge on the ultimate sporter to rest of range? Got 400s and Hft500 and its a nightmare to read in less than perfect light, the colour code system would be so much easier. I guess the gauges are the same fitting so should be possible

Thanks for that link!!!

I buy a lot of pressure gauges from them for steam use and I will vouch for how good they are.
