just grab the factory accessory tikka cheek piece and throw it on to match to your medium height rings, tikka stock is pretty awesome imo, it's what I'm doing if I end up going 30mm scope or larger objective and need to go up one peg on ring height to accommodate a bloated scope profile
otherwise step up to sako 90 adventure and have it done right the first time, or sako 90 peak which isn't adjustable but quite high comb (higher than tikka) combined with low integral picatinny gives gobs of clearance for puffy objectives, I've had to come up twice on ring heights on 90 peak to align perfection, 1.8125" off bore(needs 1.05" ring) now where 1.5" off bore center is tikka t3x lite perfection (without cheek piece, but with tikka it's a struggle to get that low, talley x-low about it in 1" no 30mm option can despite shaved rail and the lowest henneberger 30mm rings which are lowest one can find it's still a full peg too high and would need that tikka cheek piece imo, the sports match t048c/084c apparently bomber set up and with that tikka cheek piece, I'd look at that option also should I decide to Hubbell it one day, I clear 40mm and align with the super low set up mimicking talley x-low
