Arisaka Defense Adjustable Inline Scout Flashlight Mount - M-LOK Aluminum

The Arisaka Defense Adjustable Inline Scout Flashlight Mount is a low-profile M-LOK rail solution purpose-built for modern tactical rifle setups where factory Scout light mounting just doesn't cut it. If you're running a quality handguard with 45-degree mounting flats—like a BCM MCMR, Geissele SMR, Daniel Defense MFR, or KAC URX4—this aluminum mount lets you position your light exactly where you need it without fighting geometry or sacrificing sight picture. The adjustable design gives you three discrete positions, each offset 0.12" to either side of center, so you can dial in clearance for front sights, optics, or other rail furniture without compromise.

The Inline Scout Mount is engineered to sit tight against your handguard: the Surefire Scout Light base rides just 0.2" above the mounting surface, keeping your overall profile lean and your balance point where it belongs. Arisaka designed this specifically around Surefire M600 and M300 series lights, but the mount plays well with a wide roster of quality lights, including Modlite OKW and PLH variants, Streamlight Protac HL-X, Olight Odin, and Arisaka's own 300 and 600 series. Made in the USA from aluminum, it ships with all necessary hardware—M-LOK nuts and both Torx button head and flat head screws—so you're ready to install right out of the box. One heads-up: you'll need to unscrew the light's tail cap to access the front mounting screw, which actually helps keep overall length as short as possible.

Whether you're building a precision rifle for distance work, a close-quarters carbine, or something in between, an adjustable light mount that lets you work around your existing setup beats forcing everything into a standard Picatinny adapter. This is the kind of small-detail gear that separates a thoughtfully built rifle from one that's just assembled.

Frequently Asked Questions

What lights are compatible with the Arisaka Inline Scout Mount?

The mount is designed for Surefire Scout Light M600 and M300 series (including M300A, M300B, M300C, M300V, M312, M322, M312V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, M612V, M622V), 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 lights.

What handguards work best with this adjustable Scout mount?

While this mount works on any M-LOK handguard, it's specifically optimized for 45-degree angle mounting flats, making it especially effective on BCM MCMR, Geissele Automatics SMR (MK4, MK8, MK16), Daniel Defense MFR, KAC URX4, ALG Defense EMR, MI Gen 3, Mega MML, and Mega/Hodge Wedge Lock handguards.

Why do I need to unscrew the light's tail cap during installation?

Unscrewing the tail cap provides access to the front-most mounting screw, which allows the mount to be installed in its most compact form, minimizing overall length on your handguard.

Can I use this mount in a cantilever position off the end of my handguard?

No. This mount is designed for standard M-LOK attachment along the length of the handguard and is not intended for cantilever use where it would hang off the handguard's end.
