Actually… almost lolSee post #40 Think I got it
I think this one would be less of a problem since it has to get past two rings instead of just one.
The one that I see is a problem is this one…
air just has to move around one o-o ring and then leak out around the seam of the block and the lower section of the frame

Don't understand what arrow is pointing at ?
But yes, pressure within throat during shot can very much travel around body of seat and I.D. of housing going out the hole that factory "Is Not" blanking/sealing where transfer path is drilled in manifold during manufacturing.
Perhaps tap the lower hole if enough meat is there w/o interfering with seat, or having housing fit frame and screw in a plug ( Say a shallow 1/8-27 NPT )

lol my poor attempted an arrow was pointing at the daylight through the bottom. Indicating that’s the hole that is possibly the culprit to my wowe’s
Wouldn’t a BSP thread do a better job of Sealing without having to use any kind of Teflon tape?
Or would that be the wrong type of application for a BSP thread?

inside 10 min on bench we have a fix ...
For you self doers ...
If you have a lathe ? .... super simple part.
O.D. is .348"
O-ring groove @ .080" wide by @ .060" deep
O-ring an SAE #011 buna
OAL @ .170"

You had reminded me of seeing noting this potential issue a couple years ago tho forgot all about it never noting an air leak .... Tho was not chasing one either.
Makes no sense factory did not address this ? As air path integrity is reliant on the near zero/zero fit of seat into housing in not having air pass around the seat ( Between o-rings ) and exit out this hole.

soooo much better than epoxy lol
I can pay you

Done .... @ 5min to spin off another while size numbers were in my head.Um….. can you make me one lol

Thanks for the measurements
I will knock one up, it's a bit of a strange one as MSR Workshop seems to have discovered this problem, yet as I seem to remember you also made up and used filler ports for the valve seat to barrel seals which in theory should increase the risk of leakage around the valve seat between the two drillings due to the extra resistance.Upvote 0
That Piece is left open from the factory on purpose. If the valve seat develops a small leak, it gives the air somewhere to bleed to, so if someone accidently left a round chambered, pressure will not build up behind it and shoot the round.You had reminded me of seeing noting this potential issue a couple years ago tho forgot all about it never noting an air leak ....

If the valve seat starts to leak, even slightly, that means air could be escaping even at low pressure—which is definitely something to keep in mind. That said, as sensitive as the Skout triggers are, if we’re walking around with a round chambered, we probably need to be more concerned about our own gun safety habits than any mechanical risk.
And honestly, if a pellet is getting sent downrange just from a leak, that’s not a small issue—that’s a serious leak.
I’m not familiar enough with how other manufacturers design their systems to know if any of them include backup safety features in case of valve failure. Of course, most of them aren’t using this kind of spool valve either, so it’s hard to say if the design inherently carries more risk in the event of a leak.
What I do love is how easy this gun is to work on. It really makes experimentation, testing, and tuning a core part of the hobby. That hands-on aspect adds so much enjoyment to owning and shooting airguns.
Thanks again, Skout, for chiming in here and for taking the time to read the forums. It’s clear you’re committed to building the best guns possible. For now, a temporary plug gives us a simple and reversible way to test how small changes affect accuracy. If it causes problems, no big deal—we just take it out.

Surely that hole can only leak from the firing cycle as the end of the spool valve has a seal and also the block has its own O ring, it's far easier for the air to leak as there are no seals between the air path from the valve seat/transfer port and the barrel transfer port, there is no O ring between either end of the drilling to prevent air escaping back.

In reflection to that statement
this is an issue not another AG design I've ever witnessed has done.It is in my opinion a slow leak and the knowledge that a loaded pellet or slug while resting in breech unfired is not making anywhere near a 100% seal to the barrel & would IMO easily have any slow leak equally pass around it w/o issue.
We're not exactly talking a cork in a bottle here

Agreed ! And for the same reasons I have stated above, a very odd one, and it doesn't add up to me!
