Arisaka 600 Series

The Arisaka Defense 600 Series Light represents a modular approach to weapon lighting, allowing users to select from current head options including Malkoff E2HTv3, SureFire KM2-C, and Malkoff infrared heads. With the E2HTv3 head, the light produces 1,050 lumens and 33,000 candela on a 16650 rechargeable cell, or 850 lumens on two CR123A cells. The low-profile 600 Series body provides an unobstructed, close fit when using Arisaka's Inline, Offset, or Side Scout Mounts. This system shares the same mounting footprint as SureFire Scout lights, ensuring compatibility with the vast ecosystem of mounts and switches.

The Malkoff heads are fully potted to withstand recoil during weapon-mounted use, with runtime of approximately one hour on a 16650 cell or 30 minutes on two CR123A batteries. The E2HTv3 is the balanced white-light option, while the SureFire KM2-C adds white/IR switching and the Malkoff EX IR heads serve night-vision-focused builds. The CNC-machined 6061-T651 aluminum body with MIL-A-8625 Type III hard coat anodizing ensures durability across harsh environments.

Arisaka's modular system philosophy allows users to mix and match components based on mission requirements, swapping heads for different applications while maintaining the same body, tailcap, and mount. This flexibility combined with competitive pricing makes the 600 Series an excellent choice for users who demand adaptability without sacrificing performance or reliability.
