This plastic mount is compatible with X200, X300 and X300-Ultra flashlight lights for use on a carbine or long gun. It is a direct replacement for the plastic frame rails and provides a shroud for the activation switch. This gives the user a positive indexing point for light activation as well as providing protection against light AD’s during use and storage without impeding access to the switch.
Note: Does NOT fit the newest revision X300U-B (600 lumen) with updated mounting system.
