The Patented Arisaka Inline Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights, the Arisaka 300, 600 and 18650 Series, Olight Odin, and the Streamlight Protac Rail Mount 1 and 2. It replaces the stock Picatinny rail adapter with a low profile mount for legacy Troy Alpha handguards.
