The Daniel Defense Offset Flashlight Mount is for use on the Daniel Defense SLiM Rail and other KeyMod rail systems. It is designed so that as the shooters forward hand grips the rail or vertical foregrip, the thumb has quick and perfect access to the rear button of his flashlight. Because the action of activating the light is quick and natural but deliberate, this setup eliminates the chance of unintentional light discharges. This mount is compatible with most common flashlights which have a 1 diameter battery tube.
