So I bought some of these off a guy on ebay who says they are foil green.... I get them they are cleary DFE. I would use them on my noveske but it came with BUIS. And when I sent him a picture saying you clearly are color blind he said sorry no returns. I believe they are gen 1, but im not sure. Anyway I can tell the difference? Asking $70 that includes shipping to the lower 48.
