Remove the slide like shown in the video, drill the two hole with your bare hands and the included drill. Now you can screw the framerail right into the SSX23.
Adapt your SSX23
With the framerail mounted your can attach a flashlight to your SSX23. This is especially handy if you play in areas that consist of tunnels, caves or dark urban environments. Another option is mounting a zoomcam, in order to record the incredibly far shots that the SSX23 is capable of.
