American Tactical Imports informed me that they will not be importing any more GSG-522 firearms. The H&K MP5-style rifle is available in a variety of rifle, pistol, carbine and suppressed configurations. Once they sell out of current stock, or on 31 December 2016, they will no longer be selling them. Magazines and repairs and warranty cover will continue.
ATI said they would not be making any further statements regarding this at this time. Thier notice does state they will continue importing other GSG firearms, including new models next year.
I am not sure what to make of this. In 2009 ATI settled with H&K after they were sued for copying their design. Last year ATI and GSG filed a lawsuit alleging that H&K never owned the copyright to the design in the first place. I have heard nothing regarding the latter lawsuit since I wrote about it in April 2014. I wonder if American Tactical lost the case and have decided to cease selling the firearm.
