Wondering. If you mounted a clamp-on ar-15 fsb on a savage barrel with a barrel diameter of .75" at the muzzle, and a detachable rear sight on a savage receiver mounting rail....would they line up?

I'm guessing in the wide world that someone from the Wile E. Coyote school of gunsmithing has tried this... so I figured I'd ask.

Just barely considering building an iron sight rifle with a very long sight radius.
