The Arisaka 600 series Light Body is specifically designed to replace the Surefire Scout Light M600 weapon lights with a streamlined form factor, omitting the stock picatinny clamp mounting interface. This design choice significantly improves clearance for front sights, particularly when used in conjunction with the Arisaka Inline Scout Mount on handguards featuring 45 degree mounting surfaces adjacent to the top picatinny rail. Key features of the Arisaka 600 series Light Body include compatibility with Scout Light M600 series tailcaps and various heads such as the KM2C, KE2A and KX2C, with full support for IR heads. The light body seamlessly integrates into any aftermarket Scout mount, retaining essential mounting holes and a square lug interface on its underside. This ensures versatility and straightforward installation across a range of firearm setups. Additionally, the Arisaka 600 series Light Body offers the flexibility to assemble a complete light system from scratch by sourcing additional components readily available from online retailers. This includes a diverse selection of tailcaps and aftermarket light heads, enabling shooters to customize their lighting solutions to suit specific operational requirements. Arisaka recommends pairing the 600 series Light Body with the Malkoff E2HT and E2XT light heads. These light heads are favored for their superior beam profiles, higher candela output compared to Surefire offerings and their American-made quality. This combination enhances visibility, precision and operational effectiveness in various tactical and shooting scenarios. In summary, the Arisaka 600 series Light Body stands out for its enhanced functionality, compatibility with a wide range of accessories and the ability to tailor lighting setups to individual preferences and mission needs, making it an excellent choice for professional and enthusiast shooters alike.
