So it turns out on my specimen of a gun, that the cylinder does not sit flush with the ribbing in the gun.
Basically the rib next to the rear stock to cylinder screw, sits higher, causing quite a few of the end/middle ribs to be doing nothing. Seems the most likely cause of why the barrel is pointing slightly downwards.
When I checked the square of the barrel out of the stock in relation to to the cylinder, closed, it was strait as far as I could see against a flat edge.
Now a good man with new dremel such as me self, would level it down.
I on the other hand (still not have gotten around to my shock gel experiment) , have instead gone absolutely mental with a silicone so the cylinder now has a silicone bed between it and the stock. This has also filled the gaps between ribs and stock.
Also built up just behind the last rib where the screw goes through stock for extra contact. Will it work your guess is as good as mine, find out in 24 hours when it cures. My theory being that I'll now have a more even dispersal of the shock and a better all round contact to stock.
Went to town on the central pin through piston, and smoothed it all down, the crap they coated it with is rough as. Hopefully now it will have much less grip going through the guide.
Haven't put trigger adjusting screw through front of trigger gaurd as I didn't realise how far back the trigger sits, that may not be viable, will see later.

All number 8 wire here!

Got bored and fired some random pellets I had.
Best were some target pellet, 14mm x 16mm at 10m.
Only 4 and just put in and fired.
Rest were about 20 to 30mm, treated the same way grab a few and fire.
Pin keeps dropping out of open sight which sux.
But for a bunch of random pellets just fired it's heaps tighter in grouping.
Now need to find a pellet to use before fine tuning.
Oh ran a self tapping screw through trigger gaurd and have probly the lightest trigger of any of the rifles.
Positively scary. Hasn't fired on closing so will leave it there.

Pete, a couple of photos for you.  I want the rear ring for my Tasco to sit at the rearward extreme of the dovetail grooves which places the lock pin and hole to suit well clear of the piston stroke and into the plastic spring stop/trigger block area.  The first yellow dot from the RH side in the pic is where the usable part of the grooves end.  The middle dot is where I'll drill for the stop. The LH mark is where the plastic plug ends which is 59mm from the open end of the cylinder.  The cylinder wall is 2.0mm thick (a little more than I thought).  After drilling make sure you clean any sharp edges from the hole on the inside or you will damage components when you remove and reinstall them.

It will complement the stock colour well Billbob.
Being a fan of the ironic, can't think of a gun more suited to the irony. 😂

Thanks Kiwi, all good to know.

Kruza, why silicone? If u were going for a “glass bedding” effect surely use something that will set solid for the cylinder to bed in? Silicone is going to wobble like jelly and offer no support to the cylinder?

I had used fibreglass bog to bed a springer years ago. I wrapped the action in gladwrap and fixed it into the stock filled with bog. It worked well. It was a wood stock I had made, so it didn't need as much as a hollow synthetic stock would need.

The other option could be to reduce any contact points to only fixing screws, OR sliding recoil reducing mounts!!!

I haven't filled the cavities will silicone. Just contact or supposed contact points.
My thinking these days is to cut the ribs down, still in shape.
Glue a thin flat plastic length to the ribs forming a to large trough for the air cylinder, then a layer of shock gel between them. Probly from a running insole.
Talks cheep, but I guess this the perfect gun to try it on.
It should absorb some of the shock waves
