It is true that there is a huge variation in the quality of these scopes...

I have seen 3 different variants of the 3.5-10*40mm........And yes the quality can vary massively....It really is Russian roulette!

As Luddite said....if you get a good un then your luck really is in

I was told by china contact that the copies were being stopped due to successful lawsuit by Leupold......obviously not the case

The best by far is the 50mm Illuminated reticle........And its not an IR that lights up the whole tube - if you know what I mean -like AGS ect....
