I bought the Redfield (4-12-40) from the Optic Zone and I believe I paid right around $200.00. The Vortex Viper (4-12-40) I bought from Cameraland and paid around $250.00. To me the Vortex is twice the scope,great adjustments,and glass,and a fantastic warranty. I really wanted to like the Redfield,and if i had'nt bought the Vortex,I guess I would have kept it,and worked around it. After comparing the two side by side there was no question the the Vortex was the one. A buddy bought the Redfield from me and seems happy with it. --1Longbow
