Arisaka Defense 18650 Series Weapon Light Body for Surefire Scout Lights Black
- Finish-Color:
- Flat Dark Earth
The Arisaka Defense 18650 Series Weapon Light Body is a purpose-built replacement housing for Surefire Scout Light M600DF setups, engineered to solve a real problem on modern AR builds: front sight clearance. If you're running a Scout light on your rifle and your front BUIS keeps getting shadowed or obstructed, this stripped-down body eliminates the stock Picatinny clamp interface that eats up rail real estate. That design choice opens up mounting options—particularly when paired with the Arisaka Inline Scout Mount on 45-degree accessory slots next to your top rail.
The 18650 body retains the mounting holes and square lug interface underneath, so it works with any aftermarket Scout mount ecosystem. You're not locked into a single solution; this is a modular piece that plays well with other quality components. At just 0.6 ounces, it adds virtually nothing to your setup. It ships with the o-rings you'll need to keep everything sealed and running reliably.
Built in the USA to the detail-oriented standards Arisaka Defense is known for, this light body is for shooters who refuse to compromise on sight picture or function. If your rifle's layout demands flexibility, or you're optimizing a precision carbine where every millimeter of rail access matters, this is the answer.

Frequently Asked Questions
Will this body work with my Surefire Scout Light M600DF?
Yes. The 18650 Series Light Body is a direct replacement housing designed specifically for the M600DF and retains the mounting interface you need.
What's different about this body compared to the stock Surefire housing?
The key difference is the removal of the Picatinny clamp interface that comes on the factory body. This opens up space on your rail and allows you to mount the light on 45-degree accessory slots using the Arisaka Inline Scout Mount or other compatible aftermarket mounts, eliminating front sight obstruction.
Does it work with aftermarket Scout light mounts?
Yes. The 18650 body retains the mounting holes and square lug interface on the underside, making it compatible with any aftermarket Scout mount that uses that standard interface.
What's included in the package?
The light body ships with two o-rings—one #19 and one #15—needed to maintain seal and function.
