Ghost Sub 12 Ghost tinkering so far

[Sub 12 airgunners]

We have had the sub 12 .177 ghost plus for a short time now and the more i shoot it the more i like it, but as i cant help myself i have been having a play We have fitted a 580cc bottle, timed the gauges, new trigger blade, and for the inside we have made an adjustable Derin tipped hammer some PTFE spring guides and had a little polish up of the components we are now testing to see if the shot count has gone up or down and if the accuracy has changed, the shot cycle feels smoother and the action is a little quieter now for sure still early days yet but having fun so far some pics

Is the factory trigger adjustable on the ghost? Or is it like the atomic/ranger triggers?

You do have adjustments on the ghost trigger

You do have adjustments on the ghost trigger

Glad to hear. Have you found it to be a good trigger? Or does it still need some work to be considered match grade? Coming from taipans and evol’s, even my FX triggers just don’t seem up to par any more. Lol

In that case you will find OEM trigger a turd i believe Not a bad trigger, not creepy, just heavy - nothing a lighter spring and few adjustments can't fix. But a Taipan it will never be.

How did you "time the gauges"? I ordered a 25mm digital gauge from Huma and figured the right sized o-ring would help me time mine. Once I removed the factory gauge and realized that the air is introduced into the side of the bore just below the threads, I kind of figured that using an o-ring would be futile attempt since it would block the air from getting to the bottom of the gauge. Since the factory gauge used a Dowty sealing washer, I simply reused it on the digital but didn't tighten it up completely because the gauge was going to be maybe 30⁰ out of alignment. I left it a smidgen loose and it held 225 bar overnight, but if there's a better solution, do tell.

Well, that's pretty much exactly how I clocked my Reg side gauge. I was a tiny bit perplexed when I saw the passageway just under the threads knowing o-rings size under the base of the threaded part would probably only obstruct air altogether. Sealing washer less than ¼ turn from bottom out hand tight did the trick. It's been holding pressure ever since but if it begins to leak, a thicker sealing washer will be needed.

What size are the Dowdy washers you used and do you know anywhere they can be bought in the different thicknesses as i've only been able to find multi packs of the same size?

I believe they're ⅛ BSP, which is the same as ⅜" American standard and 10mm Metric standard. As far as thickness, I did not measure mine but I have seen different thicknesses online, on Amazon, and other places. I wish I could say "buy this", but I can't.

As IRBent says 1/8 bsp or m10 can work and the different thicknesses are just different makes, we have a fair few in the work shop so we just rummage around
