Quick background - I bought a used FX dreamline bullpup and it was shooting quite a bit slower than FX told me it should based on stock, not even having a plenum, which it has. I ordered a new stock spring and a wika guage. I degassed by letting the main pressure gauge bleed off very slowly, put in the new wika, and tried to fill it with air. I got to about 55 and it starts leaking air between the plenum and the main tube. I tried cocking and even shooting while it is filling and it won't stop or even slow down. I'm using a yong heng to fill.
It removed the air tube and the power plenum and to me, the o-rings look pretty flat in the groove as they barely stick up out of the groove. Since I have it open, what will be the fastest way to get a pair of o rings for the plenum and tube? (each seems to be the same size but I'd like to be sure).
I assume it is one of those "don't degas it because it may unseal" kind of things but maybe I'm wrong.
