Quick little update, the reg was fine. The guy who owned the gun before me had screwed the back block all the way down on the rod, and it caused the air passages to not line up. It would shoot fine without holding the pump handle but shoot around 70fps while holding it.
I didn't notice this until I got to the field and was experiencing the same problems with a different reg.
EDIT: Question, how many turns out should the back block be out from flush on the rod or down on it?
Okay now I am really confused, it seems like all other S6.5s has the block threaded all the way down, so why is mine giving me these issues?
