I have a Nikko Stirling Gold Crown for many years now this one is 4-12 x 40mm objective lense , one of the best scopes I have , I also have 3-9 illuminated reticule , not a GC , but still a very good scope .
There are many different models of the GC , there is also the Silver and Platinum models I dont think you can go wrong with any of them . Dave
