Arisaka Defense has made its name on high-quality illumination and mounting products. The 300 series is their flagship weapon-light, designed to give you the best illumination for a rifle-mounted flashlight. The Arisaka Defense 300 Series Momentary Weapon Light uses the Malkoff E1HT head with a TIR lens for 23,000 lux at 1 meter. That gives the 300 series an incredible range with its focused beam, though the 325-lumen projection guarantees plenty of spill.

  • Highly Focused Malkoff E1HT Head with TIR lens for 23,000 Lux output
  • Durable, duty-made construction
  • 325 Lumens of white light at 1.2 hours runtime
  • Compatible with CR123 batteries
  • Momentary-On Tailcap

Momentary Tailcaps are a common choice for tactical groups that only want short bursts of light to identify targets without giving away the user’s position.

Best Weapon Light


The Arisaka 300 Series is one of the best weapon lights around. All of its parts are interchangeable with the Surefire 300 making it easy to swap parts with. Where this light stands apart is the Malkoff headlamp which projects a concentrated beam in the center with a wide range of spill.
<br>The Arisaka mounting options are fantastic. My favorite aspect of this light is probably the weight which is barely noticeable. If you like the Scout 300, you will love this light. Better quality than the Surefire 300 and all of the reliability and mounting options.
