The Arisaka 600 Series Light Body is designed as a streamlined replacement body for Surefire Scout Light® M600 weapon lights. The 600 Series Light Body is manufactured without the mounting interface for the stock Picatinny clamp. This greatly increases the clearance for front sights when used in combination with the Arisaka Inline Scout® Mount on handguards with 45 degree mounting surfaces adjacent to the top Picatinny rail.
The 600 Series Light Body is compatible with almost all E2® series and Scout Light® M600 series tailcaps and heads like the KM2A, KE2A, and KX2C. It will also fit in any aftermarket Scout® mount, as it retains the mounting holes and square lug interface on the underside of the light body. The older KM2 IR head is not compatible.
It is also possible to build a complete light from scratch by sourcing additional components. A variety of tailcaps and aftermarket light heads are available from online retailers. Our favorite light head to pair with the 600 Series Light Body is the Malkoff E2/Scout, which is compact and made in the USA.
