Looks like my M600U that I bought last year. So I would say it is legit just by what I know. Surefire has changed the wording and style of the font over the years, also the letters/numbers on the head denote the model and output.
As far as the attachment, hand tighten it pretty much how to do it, maybe an extra quarter turn with a coin. I put witness marks, usually with some white paint, to be able to check to see if it has loosened since I have seen more than a few Scouts hanging from rails by pressure switches because they came loose. I like my Larue mount to solve that issue. And there are a number of other rail mounts that are not too pricey that can solve that as well, but you lose, if it matters, the relative ease of pulling the light off the weapon.
