The CMPicon sells a scope mount base that replaces the rear hand guard. It requires a long eye relief scope and, since the scope is forward of the receiver, you can load the Garandicon normally. With a decent scope and presuming your rifle groups 2 MOA or less, your effective range on dear-size game would be about 250-300 yds. I say that taking into consideration the typical Garand trigger, typical 2.5x - 4x power of long eye relief scopes as well as the accuracy potential of most Garands. YMMV.
