hello friends I have a problem with my fx impact the problem is the next when I try to load it full air is not beyond 150bar and it is something strange because when I close the tank valve scuba the pressure of the pressure gauge tank begins to fall to 150bar I already make sure that no leaks there I disconnect the filling station and the pressure gauge of the rifle tank indicates 150bar I shoot and drop abruptly to 100bar and it stays that way even if the shot continues
