This may seem like a dumb question, but I've just received my Leupold Mark 4 with 30mm tube and now starting to shop for a set of tactical rings. Looked on the web and its like going to a candy store - every Tom #### and Harry produces some sort of tactical rings. I've heard some are great others need to be reamed - stay away from aluminum - get steel - get quick release - don't get quick release. My intentions are 900 meters. I'm also going to need mounts - thinking on the lines of steel cant decide if I should get one piece or two. Oh help Oh help Oh help...............
