[QUOTE="lightwind, post: 574917, member: 30140"] I suggest you do a little sluthing. Have you examined the ring marks on the scope? They can, sometimes, tell you something. For instance, if they are even around the tube without any visible longitudinal scratches it indicates that the tube was bedded evenly. If you can use a magnifying glass (low power about 7 power) and can see clear marks that run down the tube in the ring marks it means that the inside of the rings is not perfectly circular. This is where the cost of the rings comes in. Lesser quality rings are not cut as near a cylinder as better rings are (note I was very careful to say lesser quality not lesser cost because they don't always mean the same). I have come to depend on high quality CNC manufactured rings and I check them but have never had to lap them. I also like combined base and ring sets such as Aadland mounts. The question was asked as to why pay more for mounts and rings. The reason is the precision of the hole that your scope goes through. It must line up and must have a large part of the surface area touching the scope tube. The lining up is taken care of when the mount and rings are one piece (and precision manufactured). The surface area is taken care of by using precise numerically controlled mills. You do pay more but the rings don't slip or scar the tube. I looked closely at a scope tube a friend had mounted with the mid-range Leupold mounts and found a slight grove where the scope rings ended. I looked at the mount and found a slight raised section at the back of each ring. He had not lapped the rings, but the size of the raised section was well beyond the limits of normal manufacturing technique. Even lapping would have been problematic. However, I have two sets of Leupold Mark 4 rings that never need lapping. The bottom line is find a reliable vendor with precision rings and pay a little more. I have complete faith in a number of manufacturers and the one I use now is Aadland because they seem to be as rugged as any I have ever tried. [/QUOTE]
