I haven't done anything to it. Came with a full tank of air. Like I said the gap along the tank is even until the gauge. This not worthy I haven't even shot it yet😢 The shroud does seem to have a little wiggle to it. Could the gauge just be off if so are they removable?
Mine looks like its up against the shroud right by the gauge. And I just got mine back from Hatsan for warranty work.
