The Arisaka 18650 series Light Body is crafted as a streamlined replacement specifically for Surefire Scout Light M600DF weapon lights. Notably, this version of the light body is designed without the mounting interface for the stock picatinny clamp. This deliberate omission significantly enhances clearance for front sights, particularly when the light body is paired with the Arisaka Inline Scout Mount on handguards featuring 45 degree mounting surfaces adjacent to the top picatinny rail. Moreover, the Arisaka 18650 series Light Body maintains compatibility with any aftermarket Scout mount by retaining the essential mounting holes and square lug interface on its underside. This ensures seamless integration into various firearm setups, allowing for optimal placement and minimal interference with other accessories. These features make the Arisaka 18650 series Light Body an ideal choice for shooters seeking enhanced functionality and versatility in their lighting solutions for tactical and shooting applications.
