Good luck finding one like that, those were sold 12-15 years ago. A lot has transpired for GSG since then including some gaytf flexing and a lawsuit or ten by HK. They have changed quite a bit since those days. I had one of those original runs and the suppressor wasn’t “fake”, the barrel ran all the way through it BUT you could unscrew it and the sleeve would come off. If you wanted to chop the barrel and build some kind of homemade stack in there, it would have been super simple to do. The new ones are all sealed up I believe
