So i had bought a G6R off my friend, it worked perfectly for a month and now is starting up with some odd things. The fps is all over the place, randomly breaking balls. I just used the lpr tester and set the lpr to 80, the high pressure gauge on it was set to 180ish i think. I just aired it up to check if it was working, and the bolt is just clicking back and fourth like theres not enough air to move the bolt. Any suggestions? and how do you go about adjusting the high pressure regulator? wont the high pressure be different depending on what fps you are shooting at? thanks!
