Not that I dislike the mounting setup, not the worst I've seen. However, the metal quality of the Redfield base screws just plain sucks! I had a mom and pop sporting good's store mount a scope using Redfield bases and rings years ago. I later decided to replace the whole setup with a new Leupold scope and Leupold dual-dovetail mounts. The guy that mounted the scope/rings/base had stripped one of the base allen screws slightly. I then tried removing the screw during mounting the new scope and the base screw rounded out on me leaving me the only option I had ~ using a drill and EZ out bits to back the screw out. Talk about nervous. I got it out and didn't mess up the threads on the action's receiver. However, I would recommend Leupold's dual-dovetail system as a top-notch system. I bought a Wheeler Engineering lapping bar and scope alignment kit from MidwayUSA for around $35.00. It was probably the best investment made to date.
