Nishiyan 240 demonstrates how the Tokyo Marui AK47 NEG Auto-Stop Function in this video... "Marui's next generation AK 47. I was wondering if it was going to be the end of the year, but I was surprised quite early. The first auto stop function of the next generation AK series was installed. If it runs out of bullets it will stop working, the next bullet will not shoot without pulling the bolt handle. (You can also cancel this function.) Using the adapter you can use the standard electric magazine. (Auto stop will stop functioning) It is also good that it is relatively inexpensive as the next generation electric gun recently. In the future, I would like other such next generation AK series to be equipped with this mechanism and renewed. "
