I have a couple sets of Sako Optilok rings and bases for the factory Sako/Tikka tapered dovetail mount originally bought for my TRG-S M995 but never used. One pair is 30mm, medium height stainless and the other pair is 1" medium height blued, both for long action. $175.00 plus ship for the stainless, $150 plus ship for the blued or $300.00 plus ship for both.
