Arisaka Defense Weaponlight Body for Surefire M300/M600 Scout Lights

The Arisaka 300 Series Light Body is a high-quality replacement body for Surefire Scout Light M300/M600 weapon lights. It has been designed with a streamlined and lightweight design that makes it an ideal upgrade for Surefire Weapon Lights or building your own flashlight setup. One of the standout features of the M300/M600 Series Light Body is that it is manufactured without the mounting interface for the stock Picatinny clamp, making it more low-profile and streamlined.

This design choice also 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. This means that you can use this light body with a variety of different mounts, depending on your specific needs. The key difference between the M300 and M600 body is that the M300 uses one CR123 battery and the M600 uses two CR123 batteries. Make sure to check your light head to make sure you get the correct body size/length.

The M300/M600 Series Light Body is also highly compatible with Scout Light M300/M600 series tail caps and heads like the KM1E, KE1A, and KX1A. IR heads are fully supported, which is great for those who need to use night vision equipment. Additionally, it will fit in any aftermarket Scout mount, as it retains the mounting holes and square lug interface on the underside of the light body. This makes it a very versatile upgrade that can be used in a wide variety of situations.

If you’re looking to build a complete light from scratch, the Arisaka M300/M600 Series Light Body is an excellent starting point. Additional components like tail caps and aftermarket light heads are available here.

In conclusion, the Arisaka M300/M600 Series Light Body is a top-quality upgrade that can greatly improve the performance of your rifle. Its lightweight and streamlined design, combined with its high compatibility with a variety of mounts and tail caps, make it a versatile and functional addition to any tactical or hunting setup.
