Scopes and lever actions just don't go together! :-D
Look into Williams or Ashley reciever sights and open the door to a handier, faster shooting rifle that is lighter to boot! I have a Williams reciever sight on my Marlin 1894S and would go to one for a Big Bore as well.
BTW, I can outshoot my scoped .25-06 bolt action with the 1894 setup with the reciever sight out to 150 yards in field positions! :shock:
