I have not tried Redfield sights. I called and asked if Tech Sights made sights for the 336, but they do not so I went with Ranger Point. Have you tried the different aperture inserts? I want to but haven't pulled the trigger yet. Also I see you graduated from my Alma Mater about 10 years after me. No one snatches defeat from the jaws of victory quite like the pack. At least they're putting out some good research.
