I asked this over on Rifles too, but am looking at the Leupold "ringmount"? I can only "assume" it clamps onto the receiver grooves, like a .22 scope? Am I also assuming that the Medium height is the same heaight above the bore as their "STD" bases/rings? I want to stay away from Talleys/Optiloks for now, and not sure what heaight to get with the DNZ, but haven't even found a DNZ for starters. Caliber is .243, so not worried about recoil and won't "throw the rifle in the back of the truck w/o being cased, ha.
