Yi Workshop takes a look a the VFC/Crusader Tech Two-Stage Trigger for airsoft use... "On real steel, the Two Stage Trigger conversion kit is very common, but on toy guns, especially the AR type GBB toy guns are rare. So to a certain extent, VFC launched this two-stage trigger kit this time, which can be regarded as a milestone. What is a two-stage trigger? How is it different from the traditional one-stage single stage? How does the VFC group actually feel it will be used? What should I pay attention to when adjusting? This video will answer your questions."
