Zee Signatures are great if you're paranoid about ring marks or if you have a dimensional issue of some kind. You can use the offset inserts to compensate for cattywhumpus receiver drilling and other problems. The inserts WILL hold the scope very well.
My savage was not drilled and tapped true from the factory, I used these rings to mound my scope.
I had to torque the ring caps 3 times to get it where the reticle was level/plum, but past that have no complaints with them what so ever.
