Update: I tried soaking with silicon oil, won’t budge. When I get into the one way valve, what would I be looking for or what should I be doing to get it back up and running? Thanks for all your help.

Love seeing these low fpe clean kills, great shot!

Tore into the check valve earlier and replaced the o ring. 99% sure it’s the fill valve in the rifle now.

I will try the silicon oil soak as a last resort before tearing into it, thanks. Funny thing is that this thing is practically brand new, except for the few shots that I took with it when I bought it (no chance for moist air to be filled into it).

Update 2: Good news I found my compressor that was missing during my move. Bad news, the power supply blew (audible pop inside the supply box and complete loss of power, rifle gauge wouldn’t budge and mistakenly thought it would build pressure slowly) within a few minutes of trying to supply air...

Update: Was able to get to the check valve. Cleaned it out and installed a new silicon greased o ring, re assembled and same issue. Also tested with the dummy plug, can only get it to pressurize up to 2500ish psi before it stalls. Whatever is wrong with it, is beyond my mechanical abilities...

Was able to get to it thanks!

I would say it gets stuck at around the half way mark. Yes, exactly, pressure builds up in the line and can’t pump any further than that. I will try to tear into it later, thanks.

Yes, full body weight (170 ish lbs). Im guessing the pump is the issue also. Will likely look into it tomorrow. Thanks!

I will try that, thanks!

I will try that tomorrow in the morning thanks. Trying to think everything through, but it seems like it just stalls as soon as the pressure builds up in the fill line.

Could be, but seems odd since it’s not anywhere near empty.

I acquired a .177 atomic late last year. Came pre charged, shot two mags out of it, checked for leaks and put away during the unexpected busy work season. Now I came back to it, but can’t pump it to save my life with a four uncles hand pump. Pumps up just fine until the line builds pressure...

Because the ones that get into the habit of raiding native songbird nests during nesting season on my property have to go.

About a 10 lb possum, lower neck/throat shot with a predator polymag.
