Thread: Bushnell fake?

I know this is an old thread, but back to the topic, I think there are still heaps of fake bushnells on trade me now.
I tried one of my mates AR with a bushnell AR scope, the feeling is a bit odd, and not like my old bushnell AR one, which I got from a local gun shop. Then I did some research and I can 60% sure that is a fake one, but very difficult to identify.
Just wondering, is there any official way to check? Like the NZ dealer's database and so on? I really hate those low life sell fake scope with the market price.
My mate's one purchased during the Xmas last year.
