Things I liked: The rings are made from a single piece of aluminum. Due to the dovetail, which is machined on my rifle, the extending ring makes for a better fit on my scope. The four dovetail mounting screws allow a very tight grip, and the four ring screws allow the scope to be tightened with no possible movement.
Things I would have changed: nothing I would change.
What others should know: This project was for my new Ruger American Rimfire, .17HMR. The layout of the dovetail or screw mounts are a bit tricky depending on the objective size of the scope. These rings, and I'm sure their are others which can accommodate this configuration. As I said, these offer proper mounting of my scope.
Things I liked: fit and finish excellent
Things I would have changed: allen wrench supplied needs to be a bit bigger
