We are just so full of helpful advice! If you do go with an original sight it will only be accurate at 100 yards or whatever you set your front sight for (I might go for 150 yd zero). Grandpa's for that cut off switch.  I think they may be different for the 96 receiver. If you end up using the scope and the cut off is in the way a piece of steel could be fitted and filed to shape to allow cartridges to feed freely and without damage to the rims, I think I have heard of the right size nail being filed to shape for this.
