So I'm getting a Sako 75 Varmint .243; currently I think it has the Sako Optilock base and rings for a 1 inch tube. The deal on the rifle was w/out the scope, so I had to get my own scope. I decided on a NightForce 3.5-15x50. What are my options as far as mounting this scope? I'm sure I'm not the only person with a model 75 that has had this predicament. Here are pictures of the base and rings. Do y'all think I can get some Optilock rings in 30mm for the right height and the done with it? Is that how these bases work? Any help would be much appreciated. Thanks in advance.
