BTW, here's some pictures of what it is:

This is the "beefier" metal one, no plastic here! All aluminum machining, good quality rail screws, etc. Even the threading of the allen wrench adjustments was solid and clean. Four different reticles, two colors (green and red), three intensities per color. They said it was tough, as good as Aimpoint or Ultradot, and that it could be abused. Even challenged them if I could drop it, said "mei wan qi" - no problem. So I did - 3 feet onto concrete. Small nick, that was it.
So I grabbed the two good ones they had, and told them to get a few more in on Sunday. Got them at 300 RMB each. I'm glad to pay 3X the price for the solid aluminum construction that took a 3 foot fall on to concrete. Nothing worse than having a sight fall apart! Also threw in two lithium 2032 batteries.
And no, they're not really Aimpoints...
Last photo shows one of the green reticles down the view - crisp and clean.
Also picked up
two of these, one for my Susie, and one for a buddy... 200 RMB each. Plenty bright with the reticle illumination, 3-9 range, and really fine adjustments on the crosshairs. Have a different reticle, a range-finding reticle inside (mil-dot cross-hairs with multiple range gradient lines below the center).
