In my first post, I assumed that you were asking for an ahistorical option to change the site in flight. I objected because I value realism and historical accuracy. In my second post, I thought you might have known something about a gunsight that I did not, so I asked. Both times I was under the impression that you were talking about gunsights that could switch modes during flight, something I am not familiar with during World War Two (excepting the K-14, which could switch between static and gyroscopic sights). This is where the confusion lies.
