Hi Steve, thanks for sending the link! I wish I'd have seen it before. 
It just goes to show there's many ways to peel an onion, as I've taken a different approach. I understand that each rifle will have its own idiosyncrasies and machining tolerance variations, but here's what I've done to mine with the goal of a consistent, precise and smooth release of the ball bearing from the detent upon firing
The above shows "sled refinement #3" using steel to space behind the o-rings. For the previous sled refinement #2 , I used PFTE washers:
Also, I've eliminated the fwd-aft movement of the steel rails via shims between the circlips and outside of slide bracket. It took several different shim thicknesses to get it right but now there is no noticeable movement of the rails fwd/aft - which in my mind means the recoil managing sled system will work even better.
I also polished both spring ends (detent force adjustment) finished with 2000 grit and oil, but went a step beyond: The pic below will give you an idea of what was done. The final result is much different, especially when everything was measured and cut.
I learned a lot in this process, and I'm confident that this detent adjustment spring and rear slide now can perform with greater consistency and uniformity in terms of how both act on the ball bearing. Adjustment of the detent force is free and unobstructed.
Onwards & upwards- more shooting to do and more refinements to be made

. Nice work so far on your 54
pellets, for the best downrange acoustic performance
