I replaced my scope with an Aimpoint 9000SC after last spring's season. The reason was for more eye relief. It takes just once getting hit between the eyes with a magnum loaded scoped 12 gauge to know what I mean! It took me 13 years to find out but just one fleeting moment of poor shooting form taught me a painful lesson. I won't be going back to a regular scope on my 870 anytime soon! The Aimpoint gives me 4" more eye relief over the Leupold Vari-X II 1-4 shotgun scope that it replaced. I think I'm gonna like it!
