If you are convinced that you need a scope on a 470, I would most likely consider the claw mount. They are expensive and who ever you choose to do the work should really know what he is doing. As far as scope selections go, I have Zeiss, Schmidt & Bender, Leupold and Swarovski. To be honest they all work perfectly and have never given me a minutes trouble. The Schmidt is very rugged and seems to be immune to recoil. It is somewhat heavier than the other scopes.
