Arisaka Offset Scout Mount for LWRC - Precision Tactical Light Mounting Solution

The Arisaka Offset Scout Mount for LWRC is a purpose-built low-profile light adapter designed to mount tactical weapon lights directly to LWRC direct thread handguards without adding bulk or obstruction. If you're running a modern tactical rifle build with an LWRC handguard and a Surefire Scout Light, Modlite, Streamlight, or compatible optic-ready light, this mount solves the real-world problem of keeping your light tight to the gun while maintaining clearance for optics, front sights, and PEQ lasers.

At less than 0.20" thick, the Arisaka mount replaces the standard Picatinny adapter with a compact solution that positions your light at a 45-degree angle, tucking it tight against the handguard. You get three lateral mounting positions spanning approximately 0.240", so you can dial in the exact standoff distance that works for your setup—critical when you're balancing a light around an AN/PEQ-15, NGAL, or top-rail mounted optic. Whether you orient the mount upward (1:30 or 10:30 o'clock) or downward (4:30 or 6:30 o'clock), the offset positioning keeps the light body compact and your rifle's profile clean.

Built from 6061-T651 aluminum with MIL-A-8625 Type III hard coat anodize, the mount is both tough and featherweight at 0.4 oz. It's compatible with a wide range of scout-style lights: Surefire M300 and M600 series, Modlite PLH and OKW, Streamlight Protac Rail Mount, Olight Odin, and Arisaka's own 300, 600, and 18650 series bodies. The mount ships with the necessary screws to attach your light; you'll need an IP20 TorxPlus driver and a T9 Torx driver for installation (neither included). Recommended torque is 30 inch-lbs for M-Lok screws and 20 inch-lbs for light body screws using Loctite 222 or 243. Made in the USA and covered by U.S. Patent No. 11385026.

Frequently Asked Questions

Which weapon lights are compatible with the Arisaka LWRC Offset Scout Mount?

The mount is compatible with Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, and M612V; Modlite PLH, PLHv2, and OKW; Streamlight Protac Rail Mount 1, 2, and HL-X (non-laser); Olight Odin; CD REIN; and Arisaka 300, 600, and 18650 series light bodies.

What tools do I need to install the Arisaka LWRC Offset Scout Mount?

You'll need an IP20 TorxPlus driver to install the mount onto your handguard. If you're moving an existing Surefire Scout Light, you'll also need a T9 Torx driver to remove the stock Picatinny mount from the light itself. The mount includes the screws necessary to attach your light body.

How does the 45-degree offset positioning help with my setup?

The offset angles the light away from the top rail, creating clearance for optics, PEQ lasers, and other top-mounted accessories like the AN/PEQ-15, NGAL, or LA-5. The three lateral mounting positions let you fine-tune the light's distance from the handguard, so you can tuck it tight or gain extra clearance as your build requires. This is especially useful on rifles with larger front sights or stacked top-rail gear.

Does the Arisaka LWRC Offset Mount fit my specific light head?

The mount accommodates standard scout-style light heads listed in the compatibility section above. The Arisaka mount works with larger Modlite OKW and PLH heads as well as the full range of Surefire Scout Light models. If your light is in the compatible list, the mount will fit; if not listed, check the product documentation or contact us for clarification before purchase.
