If your thinking about buying a new scope for your shotgun, you should look into one that is actually designed for a shotgun. These scopes have longer eye relief than a center firescope, and a parallax setting of 75 yards in lieu of a 100 yard setting onstandard scopes. I have a Nikon Prostaff 2-7x 32mm shotgun scope that works out very well on my Rem 870 slug gun.
