http://www.leupold.com/products/scopes.aspThe beauty of Leupold...is their non-critical eye relief...you don't have to be perfect in the box to see thru it fully...and moving rearward it's still clear...Also it is the best warranty going...and..you can send them back in a change reticles in them...
