well, obviously you are going to need rings. as it's a mkii, i assume, it came with bases, so you probably will not need them.

i suggest going with a DIP one piece 25 MOA base though while at that point. there's more than enough slope added to get you out to 150 and much more if you should choose to do so without hit the end of the adjustment clicks. plus the one piece base is of the picatinny type, which gives you several option to mount your rings / scope to get the eye relief just right. if ever you want to add a level, a rail mounted style goes right on. plus the base looks cool.
