I too order a Vortex Viper 4 X 12 V-plex scope from Doug and have been very pleased. I mounted it on my 300-WSM. Great service and very quick turn around on getting my scope. Like the features of the Vortex. Very clear. I especially like the Mag-view adjustment lever. It is very easy to quickly adjust the power settings.
This is my first purchase from Camera Land and it will not be my last.
