The Arisaka 18350 series Light Body is designed as a compact replacement for the Surefire Scout Light M600DF weapon lights. By accommodating an 18350 cell instead of the longer 18650 cell, this streamlined body reduces the overall length by more than an inch. Unlike the original, the 18350 series Light Body does not include the mounting interface for the stock picatinny clamp. This modification significantly enhances clearance for front sights, particularly when paired with the Arisaka Inline Scout Mount on handguards featuring 45 degree mounting surfaces adjacent to the top picatinny rail. Importantly, it remains compatible with any aftermarket Scout mount by retaining the mounting holes and square lug interface on the underside of the light body. These features ensure improved versatility and functionality, allowing for optimal placement and minimal interference with other accessories when configuring your firearm setup.
