ARISAKA INLINE SCOUT MOUNT KEYMOD

The Arisaka Inline Scout Mount for KeyMod is a low-profile weapon light adapter that lets you mount Scout-class lights directly to modern handguards without rail real estate. Built for the Surefire Scout Light M600 and M300 series, Arisaka 300, 600, and 18650 series lights, Olight Odin, and Streamlight Protac Rail Mount HL-X and Models 1 and 2, this mount replaces the factory Picatinny rail adapter with a compact solution purpose-built for KeyMod slots. If you're running a modern free-float handguard with angled mounting flats—like a Bravo Company KMR, Daniel Defense MFR, Knight's Armament URX 4, Midwest Industries Gen 3, or Mega MKM—this mount lets you keep your rail sections clear for other gear while positioning your light exactly where you need it.

Machined from 6061-T651 aluminum and hard-coat anodized to Type III specs, the mount is durable enough for serious use. Installation is straightforward with BCM's inverted KeyMod screws and dual recoil lugs that lock the light solid to your handguard. The twin lugs also make installation easier than traditional setups, reducing frustration when you're building or modifying your rifle.

This is an accessory-only mount—it requires a compatible weapon light to function. You'll need a T15 Torx driver and a T20 Torx or IP25 TorxPlus driver to secure everything during install; neither is included with the mount. If you're upgrading an existing rifle with a KeyMod handguard and a Scout-class light, this is the most direct path to a clean, low-slung setup.
