I just purchased a brand new Nikon M-223 3x12 BDC on Amazon Prime for $345. NutnFancy (see YouTube) put this on his M&P 10 in .308 and loved it so much, he also listed it as one of his top 5 scopes. It will arrive at my home tomorrow. He didn't like the Nikon M-308 4x16 as much, but that was many years ago. With that, there is a scratched Nikon M-308 on Amazon Prime right now for $370ish. If it is just cosmetic, that is a steal. Their return policy is excellent, so if you don't like it, just ship it back. I thought of buying it myself, but hard to explain to the wife - 2 scopes in 2 days.... ha....
