Old Elk hunter you haven't even tried the Buris Sig. Zee rings rings from the sounds of things. Don't knock something unless you have the facts. These are Weaver style. If you tried to twist them into place you have a serious problem. They slide on like a Picatinny rail. Sure there are better rings out there but for the money these are pretty nice. If you are looking for the best go with the Badger Tactical rings. I'm just saying instead of spending $150 for Badger you can use the Burris and they will not mark up any scope you put into them. Oh yea did anyone say self align no lapping needed.
