Wondering exact model and when it was manufactured. Serial: AOC16713 I liked the colors so I got it a year ago. Shoots inaccurately. Back strap does not work either. Fully disassembled it and couldn't figure anything wrong with it. Put it back together and still does not work as a safety. Still fun. Just curious about it's background so maybe I can have a good reference if its worth doing any real work to it.
