Adjustable rings
The discussion on optically centering the scope got me looking for rings with windage and elevation adjustability. here are the ones I have found.
The burris signature – these are split ring design with a plastic insert, You can buy off set inserts. This is how they are adjusted. Rotate the insert and you can shift the point of impact anywhere 360degrees. You can use different inserts front and rear to get a combined effect. You can stack them – up in front, down in rear to get an additive effect. 1inch rings have a couple adjustment increments, but the 30mm rings only have 1 adjustment size and they do not make a 30mm signature for 22/ airgun dovetails. Need an adapter. Not too expensive, people say they do not leave ring marks but that initial set up is time consuming. The inserts dont like to spin, you need to pull the scope out, rotate or change the insert, reinstall the scope and test the result, repeat until satisfied and make final adjustments with turrets. Plus side? The strength of solid metal. No moving parts – think your scope will be destroyed before these budge under recoil or in a fall.
Sports/match atp61 and atp66. The 61 is a 30mm ring that allows elevation changes. the 66 allows both elevation and windage changes. they are designed for airguns, have my doubts that they would stand up to full on centerfire firearm recoil. The plus side appears to be that the adjustments are made with screws – you install the scope, loosen the clamps, make changes with the screws to get you near zero tighten the clamps, make final tweaks with turrets and job done. This ought to make it much easier to get a specific result with them as opposed to the burris and the adjustment process should be 10x quicker. The down side is the very design that makes them quick means moving parts, clamps and screws and what not, I am not convinced they can resist the same jolts and bumps as the burris which have no moving parts. Now the big one: cost. The ATP66 are $168 at AOA. Ouch. How do you like the burris now?
What other choices do people know about?

My zero on the Matador is 50 meters but my zero on the optical center is on the 100 meters, where the magnification is on max. The eye relief is critical tho. I use Burris Signature also. They work best on low-medium end scopes but only at 100 yards max. With regular ring I can see perfect just at 70 meters with the magnification set on max.
Off Topic!
This is why I sold my Hawke and ordered a Sightron, to be arrived on the first days of August.
Which is why my videos are on hold 😉 The gun can do so much better but I must see perfectly what am I aiming for.
The one piece ones look interesting but seem best suited to spring guns. Many PCPs need clearance for magazines or manual loading. Have you worked with the ATP61 or 66. Do you have any concern that they might get knocked out of adjustment by bumps and such? Trying to figure out if my concern is real or out of control engineering imagination.

I have the sportsmatch atp66 rings and they are nice quality and come with a lifetime warranty. I got mine on ebay from a seller in UK and received them just under 2 weeks. I think they work great but I have not used them on a powder rifle. Here is the link to the guy on ebay and I only paid $120 for them shipped.
