I have been researching these scopes and they seem very good for the price. I am speaking of a 3X9X40 Viper. Does anyone know much about these scopes and or how they compare to a Leupold VX-3, or Nikon Monarch. I assume the Monarch and Leupold ar better, but how much? If they arn't too much better i might go with the Viper considering how much cheaper they are!
