i've had my eye on them. i've heard the difference between the fakes and the real thing is not noticeable with regard to the Aimpoint clone 3x magnifier. in fact i've hear owners of both say to get the fake one b/c they're the same except the price tag
i know my fakepoint is made of shitty aluminum and i wouldn't recommend it for a duty rifle, but for the 3x magnifier i wouldn't think it would matter. a scope snob might say the glass isn't quite as clear as the real deal, but i really doubt i'd notice.
also, for my fakepoint. it came with a riser for lower 1/3 cowitness but the fucking screws those idiots from china sent with the fucking scope were too fucking long. i had to dremel them about a 1/4 shorter for the scope not to wobble like crazy from side to side. all hardware and the body of the scope is soft aluminum. again, not so good for a duty rifle's primary optic, but probably just fine for a 3x magnifier. YMMV
