Asking a favor from the group for scope mounting

My dad has a Winchester model 70 in .270. My mom wants to get him a new scope and is looking at the bushnell mp pro ed.

Any recommendations on the mounting base for that rifle? I did a little googling but most options seem to be 1" rings. I did not know if the sub would know the best route for a picatinny so I can get normal rings for it or a base/rings that would work with the rifle and mp pro etc.

Thanks and sorry for the headache, just trying to get a Christmas present for dad.
