Just some info. Some time ago Leupold changed the design of their MK4 rings, the top and bottom portions are more equal. The split is about 50% now, the top cap is much bigger and shaped different, rounded design on top. Looks pretty tough. Seem to be better finished too. Come in a blister-pack instead of those black boxes. Have to go some to beat Badgers, just thought that I would mention these changes for anyone interested, they look good. Will be interesting to see how well they line up, we usually lap the MK4's but don't lap Badgers.
