This is an experimental set-up with a Leupold intermediate eye relief scope on a mount from Scout Scopes that replaces the factory rear sight. Once I zeroed the scope, it worked very well against juice bottles at 150 yards.

In the past, I have tried various methods for mounting a traditional scope above and behind the ejection/loading port. All of them interfere with loading to some degree, and so the scout scope seems like a better optics solution for the SKS.
