cocojo, I've had good experience with the Weaver Grand Slam 1.5-5 as well as the Nikon Monarch 2-7. Currently the Weaver is on a Marlin 1895M and has performed flawlessly. A Leupold Vari-X II 2-7 is also a consideration. Many here seem to like the Bushnell Elite 3200's, but I've no experience with them.
