My son recently bought 2 used Nightforce scopes from a friend who used them on quite a few different rifles.
He had piccitiny bases on all the guns, and the scopes had rings with levers in lieu of the normal nut arraingment
for attaching to the base. On and off in seconds and with a record of the zero for each gun it wasent an issue for him.
They are so nice we left them on just to see how we like them.
Id sooner have one good scope rather than a bunch of not so good ones.
