The FX Dreamline main tube manometer is off by 0ver 20 bar. I wonder what brand FX uses for their gauges. I filled the rifle through 3 different methods and 3 different input gauges and all agree it's over 20 bar off.. Shows 20 under..If i wasn't checking both like I'm sure most people do, it would be over filled by that 20 bar mark. The front gauge is 25mm. What's everyone use? Huma? Wika? Huma made by Wika? Other?
