I put in a new spring and powertube oring. Oiled it up and everything cycles like a champ. I still want to change out the powertube tip and/or bolt just in case.
What is the lowest pressure to have a properly functioning valve? AGD's site states 800 then I read about 400-450psi and then I saw something about 375? If the mag fires at (350psi?) then I would think 450 is about as low as you would want to ever consider. I hope to hit a chrono tomorrow and see where I am for fps as well.
