My brother just gave me a BSA Supersport Magnum. I want to use it to protect my nuts ( pecans ).I found a Bushnell Elite 3x9x40, Will it hold up on the BSA springer?

CH...call Bushnell. They really are good scopes on Airguns, they can tell you if this scope is airgun approved.

Which air rifle? Some like a HW30/R7 are so mild I think most scopes would work fine. Some like the RWS 54 will eventually eat any glass you put on them.
