It's rare to watch female airsoft players do their own teching. In this Rock Rose video, they do a challenge of removing the gearbox without breaking anything... "We have a challenge with the DSG custom of APS electric M4. It will be attempted multiple timesuntil the mechanical box is taken out. Enko is a mechanically clumsy class of a girl. Even such an Enko is made to work on it until it works properly. I'm sure there are many people who are tired of opening the mechanical box, but you can also do it with a sword, so please try it."
