The REIN is the most powerful and most durable complete weapon light system on the market. It features a field serviceable lens, a field-serviceable tail cap and electrically-isolated dual-switching for redundancy. It works with all existing light mounts. And it has the world’s first 3rd generation Light Control System (LCS) including a proprietary remote switch with tail-cap integration, oriented precisely for weapon-mounted use. REIN is redefining what a weapon light should be.
