I like the Leupold Sako ringmounts a lot and never had an issue with them. One thing to be aware of with those mounts is that the screw which attaches to the dovetail goes on the left side of the action, opposite of the Optilocks. Just need to look at the way the tapered dovetail works and no problem. Have seen them mounted the wrong way around.
