I just recently got a new Tikka in .243. My problem is finding scope rings. I need some help. Are the dovetail rings exactly the same as a Sako? Whats the best way to go and not spend a small fortune? I can order Millett rings for about $28.00 if Tikka and Sako are interchageable. Will medium be high enough for a 40 mm scope? Any suggestions? Thanks alot.
