Simon of MadBull Airsoft sent this over the weekend... "Today, we are testing the GSG-01 and we put some cotton and flour insert into the GSG-01. Guess what happened…..? Check our video, you will find out! NOTE: We asked some of our visitors to play with GSG-01 today. All of them had fun! When we will release this item? After we make an instruction video next week, we are almost ready to release this item."
