Arisaka Defense 18650 Series Weapon Light Body for Surefire Scout Lights Black$51.48 – $55.89
Availability: In Stock
The Arisaka 18350 Series Light Body is a purpose-built replacement body for shooters running Surefire Scout Light weapon lights who want a more compact profile without sacrificing functionality. By switching from an 18650 to an 18350 battery cell, this light body cuts over an inch from your overall length—a meaningful reduction when mounting on short-range optics rails, AR handguards, or shotgun setups where real estate is tight. Unlike the stock Surefire design, Arisaka stripped the standard Picatinny clamp interface and machined the body to work seamlessly with their Inline Scout Mount and other quality aftermarket Scout mounts, giving you superior front-sight clearance on 45-degree mounting surfaces while retaining full compatibility with proven modular heads and tailcaps.
Built from 6061-T651 aluminum and finished in MIL-A-8625 Type III hard-coat anodize, this is a US-made precision component engineered to the same standard as the rest of Arisaka's equipment. It weighs just 0.6 ounces, so you're not making weight-and-balance compromises. The body accepts a broad range of proven light heads—including Surefire M600DF, Modlite OKW and PLHv2, and Malkoff E2XTL—and works with industry-standard tailcaps from Surefire (UE, DS, and Z68 models) and Arisaka's own momentary options. Your choice of head, tailcap, and mounting method means you're building a light setup tailored to your actual gun and workflow, not buying a locked-in package.
This is a body only: it ships with replacement O-rings and the hardware you need to assemble it, but you'll source your own light head, tailcap, and mounting screws. If you're already running a Scout-platform light and want to go shorter without losing versatility, this body is the quickest path forward. If you're building your first Scout light and want flexibility to upgrade heads or tailor brightness and beam profile later, starting with a modular platform saves money and hassle over time.
| Body Material | 6061-T651 Aluminum |
| Finish | MIL-A-8625 Type III Hard-Coat Anodize |
| Battery Cell Type | 18350 |
| Weight | 0.6 oz |
| Compatible Light Heads | Surefire M600DF, Modlite OKW, Modlite PLHv2, Malkoff E2XTL |
| Compatible Tailcaps | Arisaka Momentary, Surefire UE, Surefire DS, Surefire Z68 |

The body is compatible with Surefire M600DF, Modlite OKW, Modlite PLHv2, and Malkoff E2XTL heads. For tailcaps, it works with Arisaka momentary, and Surefire UE, DS, and Z68 models. It does not include a head or tailcap; you'll need to source those separately or transplant them from an existing light.
Yes, as long as your mount is a Scout-pattern design. The body retains the square lug and mounting holes on the underside, so it works with aftermarket Scout mounts. It is specifically optimized for use with Arisaka's Inline Scout Mount on AR handguards with 45-degree mounting surfaces, which gives superior front-sight clearance since the Picatinny clamp interface was removed.
The 18350 cell reduces overall length by over 1 inch. This is particularly useful on short-range or close-quarters setups where every bit of real estate matters, or when you want to keep your front sight line unobstructed.
The body ships with replacement Buna-N O-rings (#19 and #15) but does not include a light head, tailcap, or mounting screws. You will need to source or reuse those components separately. You'll also need to acquire a mounting method—either an aftermarket Scout mount or the Arisaka Inline Scout Mount if you want optimal front-sight clearance.
