Win/64,
There is a 2.5 X FX-11 in the Ultralightweight series. I have one with heavy duplex on my .416 Rigby. Short, lightweight, nearly indestructable and about the longest eye-relief of any conventional scope. A fine close range scope, but not good for much else. Cheap too, for a Leupold.
Don't get it confused with the FX 11 2.5 X 28mm, that is a extended eye-relief Scout scope.
