Winning bid: US $338.00
Whether it's a fake or not, it's a LOT of MONEY for a simple flip slight of any kind. Prices like this are bound to cause fakes to show up.
Maybe some collectors see value in this flip sight, but the Value-to-Risk Ratio is not very conducive to making such a purchase, especially if the our Milsurps team of experts can't draw a definitive conclusion.
For me, I'd spend my money on something with less risk attached -- just my view.
