I have an opportunity to by a Sav. Pre. Car. with Leupold Mounts/Rings & a Konus M30 6.23x25. If the scope is good, it's a good deal, if it's junk, not so good a deal. I am more interested in the rifle, but must buy package. I know it's no Nightforce or better upper end Leupold for that matter, but how good is that scope? Any personal experiences?
