The Arisaka 18650 Series Light Body is designed as a streamlined replacement body for Surefire Scout Light M600DF weapon lights. The 18650 Series Light Body is manufactured without the mounting interface for the stock Picatinny clamp. This greatly increases the clearance for front sights when used in combination with the Arisaka Inline Scout Mount on handguards with 45 degree mounting surfaces adjacent to the top Picatinny rail. It will also fit in any aftermarket Scout mount, as it retains the mounting holes and square lug interface on the underside of the light body.
