Years ago Bausch&Lomb made the Balvar series of rifle scopes. There were no adjustments in the scope at all.
Their adds also showed the scopes soaking in a bucket of water.
All the adjustments were in the mount. I had several of them and swithched them around to different guns with no
issues on scope zero.
With proper notes kept there is no reason why a good scope couldnt be switched between guns.
