Yalong Funny Workshop put out a video in late November 2022 about the MK18 Mod 0 airsoft grenade launcher, said to be the world's first... "This time I received a commission, and the other studio sent me the iron casing of the gun, asking me to design the internal mechanism.

So the shell of this transmitter is not designed by me! I'm only designing the inner workings.

This time, the Geneva intermittent mechanism is used to design, and the crank stroke imitates the real gun, which is 180 degrees per round.

This mechanism is reserved in the future, maybe it can be used as an electric fully automatic grenade launcher?"
