I bought one of these recently and bolted to a new S400 shot GP 1 with it. I have to say that the rangefinding is as good if not better than the Nikko (I have used a Mk3 for 3 years). It is also 10% lighter than the mk3, coming in just under 1kg ( the older Nikko's are at least 1.25kg heavier. You get a sunshade some end caps and a usable wheel (for £500 buy the Jon Harris not just because he's a mate of mine but because even his most basic wheel is a lovely bit of kit) and for £465 you get a great scope with a guarantee.
