I got three of the NC Star scopes. I use one on my Ruger Super Redhawk 44 mag. After a couple of hundred shots the scope is still working. I also use them as scopes for no drill and tap scout scope mounts on some of my milsurps. Consider what I paid for them I'm satisfied with the results. I'm getting .5" groups with my Swiss K-31 using a 2X7 NC Star scout scope.
