The Sight is a Real good Fake. I'm not saying anything bad about the seller. It's well known that the L is darker than the Base, but this is not what showed me it was a Fake. I did see some real ones on this Collectors SG Sights among with many others on his M1icon Carbine Collection. I took many pictures of both and I'm making a Collage on my Photo Editor for future references. He has been Collecting for 30 years and has so many Carbines and he had Several Sights in a box he put on a table showed me what to look for. (I ended up buying 4 among with so many parts) I showed him this and he took his sights out and pointed out the differences. There are a couple of other features you can look at and tell this is Fake. When I finish the Collage and if anyone would like to see it email me. Also, I agree with him about any Sight in pictures that is questionable is to have it and hold it and even though you can tell some are real through Pictures lighting and angles can be deceiving.
