This is a sector chip designed to extend air nozzle retraction. It was specifically designed for use with SHS gears, although it can be modified to work with a variety of other gears. In its current configuration it provides maximum retraction time, and in higher speed guns may need to be trimmed down to facilitate airseal. This was intended to be used with aspherical rounds to facilitate easy chambering in semi auto. This project was done in collaboration with Clandestine Airsoft.
