When doing a general cleaning of my GSG-16 this part dropped out when disassembling the basics. I did not remove the trigger assembly just the main assemblies. I can not figure out where it came from as I can not see it in any of the exploded parts views or the numerous videos I have watched trying to figure it out. If you can help please let me know where this goes. BTW I did take the gun to the range and it does work as it should without this piece installed.
