The simple answer is Sako Optilock bases plus appropriate rings.
Make sure you get the bases for Sako and not Tikka as the dovetails aren’t the same. However, Sako have stayed the same for a very long time (the only exception I can think of is anything marked for the A7 or S20).
Rings are then a case of picking the correct diameter and height.
As with anything shooting related, there are plenty of other options out there (one piece rings, rails etc) but the easiest thing to do if you’re mounting a ‘normal’ 1” or 30mm scope is the above.
