Sorry WiFowler i forgot to add: the SxS Safari big bore don't have pre equipment for scope, being destinated to hunt with fixed sights.
Yes and no . . . . the rib is D&T for an included Weaver-style base. The intent of my question was to find out if the rib would 'endure' the dovetailing process for a dovetail mount. I envision a reflex sight - Burris FastFire, Trijicon RMR, Leupold DeltaPoint, et al, on a dovetail mount thus decreasing the height above the bore(s) as compared to the Weaver-style base, and the Weaver-style clamp on reflex sight. Just thinking out loud . . . .
