    NF ATACR 4-16X42 vs X50 both F1's

    NF ATACR 4-16X42 vs X50 both F1's Is there a difference between these two scopes. I own both the 42 bell and the 50 bell. But I often see the 50 bell cheaper, is there any difference other than bell size? Why would it be cheaper, simple supply and demand ?? PB
