Plugs into the M3X or M6X Long Gun Backplate for instant momentary operation of your lighting device. Choose straight or curly cord, right-angle or straight plug. If you have the M3X with the long rifle backplate (it has a remote jack on the back), then you can use this remote switch. It WILL NOT work with a pistol backplate without the remote jack plug-in. Coiled version for longer reach, i.e. shotguns, etc.
