Looks like you were able to get down as close to the bore axis as possible, and this is a good thing. Things were simplified by the fact that the rear sight is stationary and doesn't require the clearance that would be needed if it were slide mounted and cycled back and forth with each firing. With my High Standard I had to remove the rear sight unless I wanted inordinately high scope mounts.

Thanks for adding to the knowledge base with detailed listing of parts and the excellent, clear photographs. This will be something other folks can refer to and avoid difficulties that otherwise might arise.
