Arisaka Defense 18350 Series Light Body — Black

The Arisaka 18350 Series Light Body is a shorter, streamlined replacement body for the Surefire Scout Light M600DF. It converts the light to use an 18350 cell instead of an 18650 cell, reducing overall length by over an inch. The body is manufactured without the mounting interface for the stock Picatinny clamp to increase front-sight clearance when used with the Arisaka Inline Scout Mount on appropriate handguards. It retains the underside mounting holes and square lug interface for compatibility with aftermarket Scout mounts.
