All ADM products are innovative and high quality and I strongly recommend them This ring set is perfect for a Stellarvue 50mm guide scope on top of a 4-inch refractor. The riser block keeps the thumbscrew from contacting the handle on the rail clamp. I use parallax rings for the main scope with the ADM MDS rail on top for the guide scope. It is compact and light.

Well made but maybe a bit heavy. One of the threaded holes had a large burr, but otherwise nice.
