Can anybody tell me much about these? just bought one off that site and it arrived today. The mount is a strange thing that fits the tiny Diana scope rail. The scope tube moves in the mount rather than having adjusters on the tube. There are no cross hairs in this scope and on stripping it, I cant see where any would go as the internals are plastic. Maybe there is a steel ring with the cross hairs missing? I plinked with it earlier on using it like a reflex and it actually seemed pretty accurate. It is only really for fun (OR AM I BECOMING A COLLECTOR ?) but curios for any info. Thanks
