First post, and thought this may help someone in the future.
I ran into a problem mounting my Nikon Prostaff 3x9x40 on an Axis I received Christmas Day from my wife. I ran out and bought the two piece weaver bases and medium Grand Slam rings. Got scope mounted and noticed that the rubber around the scope zoom adjustment was rubbing. I then went to open the bolt and the handle was rubbing the scope ever so slightly. Ended up switching to High Rings and problem solved. I'm sure there are many ways to alter this setup but with the design shape of a prostaff it's a bit tricky.
