I think I'll contact Trijicon with the serial number. I have read elsewhere that doing so may be a way to sift out fakes. Sadly I cannot make out that serial number, so I may have to wait until I can see it in person and then nicely explain that I would like to call first. Of course I will have to wait to Monday as well. Which is maybe what I need to do anyways because I suppose I could have been sent pics of anything. I guess working in politics and criminal law has made me cynical. If this think looked like an obvious fake to those with an eye for such thing I figured it could save me the hassle of meeting, inspecting, calling, awkward moment with seller, etc.
