Tutorial from Fulcrum to help guide you in doing a simple modification to the AUG AEG... "In this quick airsoft tutorial we take a look at my "Uberwomble" airsoft DSG build again and this time I'm explaining how I made the safety on my custom airsoft AUG into a fire selector. This allows me to lock out the fully-automatic stage of the progressive trigger so that I can fire the AUG on semi-automatic. This isn't required on all AUG AEGs but since mine has a bodged trigger I cannot use the progressive trigger, besides I hate them!"
