Solid and rugged and better design - Sako Optilock Ring Mount

Very well built, I like these better than the Sako 2pc mounts. They are lighter and simpler and still have the plastic insert in them to prevent scope damage. They have 4 screws per ring which makes keeping scope alignment easier than the two pc types when tightening the screws down. They are also a little less expensive than the two piece Sako base and rings.
