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 SSX-23.
Adapt your SSX-23
With the framerail mounted your can attach a flashlight to your SSX-23. 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 SSX-23 is capable of.
