WGP Black Magic inline reg leak from exhaust pinhole.
Piston o ring seems fine however i did not replace it. Just blows air out of the pinhole on the side of the reg. Very "mind-bottling"

Perhaps the output pressure is simply cranked up too high?

I turned it all the way in and it's still leaking.

Check the little oring under the top hat. That's probably the culprit.

i replace the oring under the top hat. i give up :( i have a spare hyper2 in my toolbag to use that matches my gun anyways. bummer

Have you tried flipping the urethane seal in the piston as well? You may need a dental pic or similar tool to dislodge the seal. A total rebuild may be easier. Here is a 2 part video.

Not that I'm an expert, but I figured for a vent hole leak it pretty much had to be either the piston oring or the piston stem oring. Maybe there's dirt/debris in it?
I applaud you for getting to the piston though... I hate trying to open those things up.

Yeah I had to macgyver a normal pair of needle nose players into c clip pliers. The shim stack seems fine and completely the way it came stock. A leak from the exhaust pinhole means too much pressure right? I need an o ring kit for this god damn thing
