i just got a used retro valve and parts kit and most of the o-rings air in good shape but really tight. They also look discolored. The trigger feels a little stiff. Im not getting the smooth trigger as some have said. They have been oiled too. Should i just replace all of them?
what is the medium input pressure for consistancy and reactivity. On the airgun sight it said there was high input, medium, and low. What is the medium around?
