I think the front mount could be combined with a Redfield rear mount, like the one already mounted on my rifle. With the Redfield front mount in place, use of the iron sights is impossible. Your front mount would eliminate that issue. As I said, I like it a lot.

As far as the bridge idea, it might allow the use of a Lyman Alaskan scope without internal adjustments (which I have) on a M-S rifle. That would be a good thing.
