I own 2 sets of "genuine" Magpul MBUS flip up sights. One in black the other in FDE. They feel like cheap pieces of crap to me, certainly not worth $90 in my opinion. Anyway was searching through ebay and see several cheapos! Most of the cheapos say PTS in the ad. Found one that said Back Up Sights at $19 so I ordered them cause I just had to see for myself. Well I got them, put them beside the "genuine" ones that I have and I cannot tell the difference! The only thing I can see is the main screw that clamps it on to the rail is Phillips instead of flat head. They dont feel any cheaper, they have about the same spring pop up tension, same markings, etc... I'm sure these are not the real deal for $19. I'd have to say they're Chinese copies. Anyone have any experience with these? Pictures added. The ones with the flat head screws, top picture, FDE picture and right sight in bottom picture I know to be "genuine". Other than that they look and feel identical to me.
