Sorry, I know this comes up a lot. I have bought a Seekins Havok Element in 6.5 Creedmoor and mounting a Z8i 3.5x28x50 with seekins rings. There is a 20 MOA rail and the scope is a 30 mm tube. I don’t have the rifle yet, so trying to figure out what height of rings to get. Swaro has a somewhat thick scope cover. Any idea which Seekins ring height to get?
