Eye Relief
We have found that generally 3 inches of eye relief is sufficient to avoid "scope eye." IF you don't get hit by the scope witih a regular stock, you won't with a COPStock or SpecOps as the overall movement is about the same. Some folks just climb up the receiver and get hit no matter what. Keep your head back and make sure that you can see the entire rear lens image.
