re: Anybody with experience with Vortex scopes?

DirtyMike, Good question. This was my biggest problem too cause my eyes go worthless when the sun is setting. Before I got the Viper I had a Zeiss which was outstanding for gathering light. On my AR I have an ACOG which is even better. The Viper series is not going to be up to par with the higher name brands for gathering light honestly. However it will and has gotten me to the end of shooting hours, so it's sufficient enough for me. The light gathering is something you sacrifice when looking for magnification. Unless your willing to spend thousands. Hope that helps
