I have solved my scope mounting problem for now. I have several Sako rifles and many Sako parts so I used two original Sako rings, both intended for the rear of the Sako dual dovetails. The rear Sako ring's recoil lug fits into the semi-circular cut in the Blaser dovetail, so there will not be any splippage of the rings in the dovetails. I filed off the recoil lug on the other Sako rear ring in order to use it as a Blaser front ring. They are windage adjustable and semi quick-detachable. I used an older 4X Swarovski scope with a duplex reticle for a perfect low fit, nearly but not quite touching the barrel at the front, and there is still room to reach the lever at the rear. When I bring the rifle up to the shoulder I am instantly aligned to the scope. So until I find something better this will do.

I also took a picture of the rifle disassembled so that you can see how it differs from the K77 and K95 locking systems.
