I just looked at the sight. It seems they are knock offs. One of the scopes listed as AO, 6-24x42 AO Tactical Riflescope, is actually this DIANA 6-24x42. Do a search on DIANA 6-24x42 and see what comes up.
100% total scam.....without a doubt....not what it purports to be. There was a similar deal on eBay not long ago, selling so called Zeiss scopes for $129. Don't fall for it.
