Inline Scout Mount

Arisaka Defense Inline Scout Mount KeyMod

The patented Arisaka Inline Scout Mount is designed specifically for lights that use the scout-style mounting platform. The mount is particularly useful for handguards featuring 45-degree angled mounting flats, such as the Bravo Company KMR, Daniel Defense MFR, Knight’s Armament URX 4, MI Gen 3, and Mega MKM. This new version is made from 7075 aluminum and uses BCM’s patented inverted KeyMod screws with dual recessions for easier installation and a secure connection to your handguard.

When the Inline Scout Mount is used on a flat 45-degree mounting surface, the user can position the light closer to or farther from the top 12 o'clock rail to make room for sights or other accessories. There are three positions available, allowing for an offset of 0.12" to either side of the center. The base of the Surefire Scout Light sits just 0.2" above the mounting surface.

Mounting Note: To keep the overall length of the mount as short as possible, it is necessary to unscrew the light’s end cap to access the frontmost mounting screw.

This mount is not intended for cantilevered use, where it hangs off the end of the handguard. Otherwise, the mount may fail if the light is subjected to a strong impact.

Compatibility with rifle scopes varies depending on the mounting position on 45-degree angle handguards:

1. Top left, 45 degrees flat: Most sights work, including the MBUS Pro, Knight’s Armament Micro, Troy folding, and Diamondhead. The MBUS Gen II works if positioned to allow clearance for the release tab.

2. Top right, 45 degrees flat: Due to the Surefire Scout Light’s asymmetrical body, the placement of the front sight and the light is more critical with this configuration. Smaller sights like the MBUS Pro and Knight’s Armament Micro work well, but the Troy, Diamondhead, and MBUS Gen II will not be able to clear the main body where the screw holes for the Picatinny adapter are located. This means that one or the other part must be moved forward or backward to achieve adequate clearance. Another option is to use an Arisaka 300 Series Light Body or 600 Series Light Body, which offer plenty of clearance.

Compatible with Modlite 183560 and 18650 housings, Surefire M300A, M300B, M300C, M600B, M600C, M600P, M600U, M600V, M600DF, Streamlight Protac Rail Mount 1 and 2, and Arisaka 300 and 600 Series. The Streamlight Protac Rail Mount HL-X is not compatible because the housing is longer and covers a mounting screw.

The mount is CNC-machined from 7075-T6 aluminum and hard-anodized to MIL-A-8625 Type III. Includes the necessary screws for attaching the light body to the mount. Requires a T15 Torx and a 5/64" Allen wrench for installation (not included). BCM KeyMod screws are protected by U.S. Patent 9377274. Cerakote provided by Weapon Works LLC. Made in the USA.
