Is it possible to mount a scope on a flattop rifle w/ a A2 FSB?
I'm looking at the Leupold 1.5-5X20 scope.
With the magnification that low, I wouldn't do it.
Anything lower than about 3X really starts showing the FSB in the scope. You wouldn't see it at 5X, but I bet you're not always gonna have it on 5X either.
I would try to get a riser of some sort like THIS from Rock River Arms.
This might get your scope up high enough to miss the FSB, but I'm not sure.
