Leaky Xvalve

[VecTor]

Seeking advice from the mag gurus

Got a leak down the barrel that I can’t seem to stop. The leak is small; gun still shoots great & holds solid 275fps. When I hold trigger leak does stop. What i have done so far with no luck.

Changed the level 10 washer & power tube oring
Changed carrier size to 1 line+dot (started with 2 lines)
Changed bolt spring with carrier (1 line +dot) lost RT effect with this
Changed carrier size to (1 line) with original bolt spring, started getting bolt stick as is it too tight.

I am using a SHP ninja reg @ 950psi. What I am missing?
Thanks for the help.

do you have a RT on/off or a ULT?

If you have shims in the powertube, remove them.

Sorry, RT on/off and no shims.

Oil? Its amazing what a few drops can do.

Replace black outside diameter carrier oring with one from a carrier you'll probably never use. Sometimes those get damaged when pressed by the threads.
