I don't know that I would waste my time with a scope on that set up. Especially one mounted to the reciever. It may not hold it's zero very well and surely will not if you remove the barrel to clean it. Not to mention I doubt the combination will be accurate enough to warrant it. See if you your beeds line up, or get some of the clamp on fiber optic sights for your vent rib. They work pretty well. Not that a scope would hurt, I just don't think you would need it in that set up.

I think this statement depends completely on your ability to shoot open sites. If you are good with open sites it is absolutely true.
If you are not I would definetely go with the scope. Even receiver mounted scopes can be rather accurate on switch barrel gun when shot at close distances.
