I currently have a Nikon Pro-Staff 2-7x on mine with Leupold Rifleman Rings- Medium height. I had a 4x Nikon Prostaff on it before I bought the 2-7x. Both of these are the "older" Pro-Staff scopes. Not vintage by any stretch but not the newer ones they sell now. When I went to sight in/test ammo I discovered my first choice, CCI Maxi-mag 40 gr jhp shoots similar to CW's, right under 1" at 50 yards. Great buy, I'm sure you won't be disappointed.
