Recently purchased subject rifle in 22-250. Want ot mount 6.5-20x50 Zeiss Conquest on it. Obviously, the supplied rings won't work (up to 40mm only). Does anyone have this combination (or similar 50mm scope & Heavy barrel)? If so, what Make and height rings did you use? I'm aware of different manufacturers of rings for this rifle, but not sure what height to order. Any feedback would be appreciated.
