I found this image online but I cannot find out who makes the magazine extension for the SCARH magazine. I even showed it to FNH Pro Shooter Erik Lund, who shoots a SCAR17S in 3Gun, at SHOT Show 2016. He did not know what it was from. He even asked one of the Belgian employees and they said it is not made by FNH.

Can any of our readers shed a light on who makes this magazine extension?

For those interested in the other items, the first item is a field care kit with a torque wrench followed by a cleaning kit and the magazine with extension. Bottom items are the ECP flash hider and blank firing adapter.

Edit: according to some people on fnforums.net, the magazine and extensions are issued items in Belgium. Odd since the Belgian FNH employee at SHOT Show did not know of them.
