Wanted to upgrade the stock Proview scope on my TenPoint Titan Xtreme so I bought the Nikon a few weeks back and will install it once the weather starts to break. I'd like to upgrade the rings too, so I wanted to ask those out there who have found a good set of rings what they used. I know just about any rings suited for a rifle would work, but they should be compact enough to provide for the short tube length of the Nikon. Also, has anyone used the Nikon Spot-on computer program for the drop marks on the reticle? Was it fairly "spot on"? I don't shoot at deer over 30 yards, but was curious if the program is actually accurate at the extended drop marks. Thanks.
