Re: sako optilock 0 moa?
If you are trying to figure out how much to lower your front ring by the most accurate way would be to calculate it using trigonometry. If your rings are 100mm apart like mine are on a size M , 85 action you will need to remove 0.58mm to get 20MOA of taper. Like it shows in my thread with the pictures I removed the material from the base because there is a locating spigot on the ring which you would not want to remove.
