The gen II Razor 4.5x27's are a proven scope, tough, problem free, feature rich with great glass and excellent value. I own two of them and don't plan on selling either. Weight may be an occasional issue for some but frankly, an extra pound of scope on your typical tactical LR type of rifle doesn't amount to anything (except maybe for the few snowflakes out there lol). Really, so your rifle weighs 17 pounds instead of 16? 15 instead of 14? Big whoop. From the people I know, many just want something new. Same reason some people trade in a 2 year old low mileage car, for something new because it's different, gives 'em that "feel good woody", it's the culture we live in. Nothing wrong with it, its just the way it is. Nothing like that new model! People do it with golf clubs to boats to homes. Plenty of NF & S&B's for sale in the PX on any given day too. There are so many new reticles coming out now that may be one overriding reason, the floating center dot seems to be very popular now as does .2mil hash marks. All good stuff. But if you're looking for a scope that can compete with any top tier model and do so at a price point that's hard to beat, you could do alot worse!
