I am the original poster of this thread and my brand new 2-7x33 Freedom scope definitely came to me with a definite groove and no sealing washer or "o" ring on the windage and elevation turrets. Leupold probably uses the washer type gasket on these scopes (when they don't forget to install them), but as I said in an earlier post, I have a few "o" ring assortments and one just happened to have some very thin "o" rings that fit perfectly in to the groove. When I screw the turret cap all of the way down, about a half turn before it bottoms out, I feel the resistance of the "o" ring. This means that it is sealing on the outside of the "o" ring instead of the topside of a gasket/washer as my other Leupolds are equipped with. That does not matter to me, as long as it seals out moisture. Besides, I live in Eastern Europe, so it would take forever and a day for me to get the OEM parts from Leupold. RJ
