Go with the optilock rings and bases.

I have a Sako 75 and a Tikka Whitetail Hunter. Both have the optilock bases and rings. I have also tried Burris Signature bases/rings and Leupold bases/rings on other rifles. I'm happy with the Leupold setup on those rifles but the optilock setup is better.

It's my opinion that the optilock setup is the best implementation out there. Easy to install, rock solid, plastic inserts to grab/protect your scope. Both scopes dropped in and were on the paper from the start. They may cost a little more but are worth it. I wish every rifle maker did the same.
