Ok, having a look at them. The screws do not have magppul on the heads, says HUA 10.9, which is a screw spec.
I do not see a PTS on either sight. The "wings" do only have 1 ridge.
So they must be clones, and I am guessing the box is cloned as well... Weird, I did buy these from a vendor in the US, not china. Maybe the price was too good to be true. Anyways, I can drop the price if needed, was trying to get my money back, but I can take a loss...
I have a TAN rear Magpul BUIS (Not Fake) that I may be willing to sell if you didn't get one yet.
What do you want for it?
