Working on an infiltration type and I'd like to add a few microdrones to him. He has the large smuggling compartments and a gun that MADs won't pick up (plastic rounds in hermetically sealer magazines too.) I'd like to have him carry a microdrone or two, but it will set off the detectors (ever other piece of cyberware he has is street legal or can't be detected without a cyberware scanner).
So can you use gun modification rules to modify microdrones or are you stuck using the vehicle rules?
