This is a Daniel Defense Mount known as the Flashlight Mount, model 03-020-16514.
Daniel Defense's AR-15 Offset Flashlight Mount (Rock & Lock) is designed for use in conjunction with a vertical foregrip which is mounted on the bottom rail. The Offset Flashlight Mount may then be mounted on either side rail for ambidextrous use. It is designed so that as the shooters forward hand grips the vertical foregrip" his thumb has quick and perfect access to the rear button of his flashlight. This setup eliminates many accidental light discharges because although the action to the on/off button is quick and natural" it is also deliberate. Their patented "Rock and Lock" one piece mounting system creating an even more robust and streamlined mount as well as simplified installation on any MIL-STD-1913 picatinny rail.
