What Chairman Jeff wanted was good gear. At the time most domestic scopes were not rugged at all in a military sense.
I use scopes almost exclusively for hunting and it's always been my experience that the problem with accuracy has been improper mounting, not the scope internals. If anything is loose, the scope will wander. External adjustments of the mounts would seem to introduce an entirely new issue with having to protect the mounts from contact and/or impact to prevent them from moving the scope.
