Also, just to clear things up a little since there's a lot of conflicting info about Haenel being Turkish, Jordanian, UAE, etc.
Their parent company is from the UAE, but my understanding is that Haenel guns are made in Thüringen, Germany. So the guns are still made in Germany, under a German brand, but with a foreign parent. In that respect, it's not so different than the US military having a love fest with FN, HK and Sig atm -- all of which are foreign held, though those aren't even American brands, for whatever that's worth.
This isn't their first gun to be sold to the German military, either. For at least a few years, the Bundeswehr's medium-range sniper rifle, the
G29 is made by Haenel as well.
