Word of caution, I almost bought a SIG TANGO 6T on here for about 600$. The gentleman told me something was weird about it, I emailed Sig pictures. They said it was a fake. I don’t know that all optic companies do this, but check what your buying. The guy selling it, I don’t believe was knowingly selling it as a fake. Hard to say, I probably won’t ever buy an optic on here again.
