Arisaka Defense 600 Series Light Body Black Rail Mount Accessory

The Arisaka Defense 600 Series Light Body is a streamlined replacement body for Surefire Scout Light M600 weapon lights. Manufactured without the stock Picatinny clamp mounting interface, it significantly improves clearance for front sights when paired with the Arisaka Inline Scout Mount on handguards featuring 45-degree mounting surfaces adjacent to the top Picatinny rail. The 600 Series Light Body works with Scout Light M600 series tailcaps and heads including the KM2C, KE2A, and KX2C, with full IR head support. The light retains mounting holes and a square lug interface on its underside, allowing it to fit any aftermarket Scout mount and enabling you to assemble a complete light from individual components sourced from online retailers. Popular pairing options include the Malkoff E2HT and E2XT heads, which offer superior beam profiles and higher candela output than Surefire alternatives and are made in the USA. The 600 Series Light Body is not compatible with the Surefire M600DF head or 18650 cells, though 16650 cells are compatible.
