Arisaka Defense | 600 Series Light Body | FDE

The Arisaka 600 Series Light Body is a streamlined replacement body for SureFire Scout Light M600-series housings that removes the stock Picatinny clamp interface for additional clearance. It is manufactured to retain the underside mounting holes and square lug interface so it will fit most aftermarket Scout mounts and the Arisaka Inline Scout Mount. The body is compatible with many M600-series heads and tailcaps and supports IR-capable heads and 16650 cells; it is not compatible with the SureFire M600DF head or 18650 cells.

This light body provides a practical solution for users who need a low-profile Scout light housing with broad head and tailcap compatibility. Its pared-down interface increases clearance for front sights in inline mount configurations while preserving standard Scout mounting features. The 600 Series Light Body is useful for custom builds, head upgrades, or when a slimmer profile is required on handguards with adjacent 45-degree surfaces.
