Yeah, Those are the PTS version. There is a company in China that is allowed to put the Magpul Logo on them. They are aimed at Airsoft and simulation type weapons. I have used the AFG2 and while I couldn't tell a difference in the way they felt in the hand, it didn't fit the rail at all. Also, when taking them apart or looking at the thickness of the polymers, there is a difference as well. The real thing isn't THAT much more and you are supporting an American Company.
