X-Valve leaking down powertube

[jewie27]

It's been about 5 years since I last used my X-Valved Minimag with ULE trigger. I recently replaced and oiled the powertube and on/off o-rings.

I'm getting a bad leak down the powertube and tried changing the L10 carrier to a smaller size. 1.5 seems to be the best when test fitted but it still leaks. Right now it's on size 1 and it still leaks. The spring is medium (red) and there are two shims used in the powertube tip.

I know it's the powertube because it pretty much stops leaking when i hold the trigger back.
Any ideas on how to get my mag working again?

try a different oring in your carrier... is that oring 5 years old as well? could be dried up or comprimised in some way not visible to the eye... That is most likely the oring causing your leak so i would continue to focus there.

EDIT: also take the shims out and see if that makes a difference.

i got the o-ring out of a sealed x-valve parts kit that was brand new. I ordered the parts kit a few years ago but never used it until yesterday.

Did you replace the carrier o-ring and oring on the tip of the powertube? Oil them both and try again. Also, as Squid mentioned, try taking out the shims.

The shims should always be removed when tuning your level 10 bolt. If you changed the oring, you will need to tune it. Use the largest powertube carrier oring that doesn't produce a leak.

thanks, I will also try to change the o-ring on the powertube tip/cap.
