It has been suggested that these mags should have HK markings on the side this is wrong, the European HK miltary mags do not have the US address or the LEO warning on them, why would they you see in Europe we dont have a hicap ban, they just banned firearms almost totally. but they bypassed magazines.
Please dont be blinkered by the regulations that we have here in the US the rest of the world is very different.
Check this PDF from HK you will clearly see no LEO markingsHK
They have the chrome follower but as to generation not sure how to tell.
