I've got a new CZ 527 in .223 Rem coming in.While looking around I considered the Nikon Pro Staff 2-7 however after a little diggin I came across the new Redfield Revolution 2-7 as another possibility.The price is the same as the Nikon but I think it has the edge.Redfield is now back in the USA being made in Oregon by Leupold.You should consider these as well.Being new there arent near as many reviews to be found compared to the Nikon but here's a link to a review from folks who's opinions (YMMV) I trust-
