Arisaka Defense Inline Scout Mount - Keymod
The Patent Pending Arisaka Inline Scout®
designed specifically for the Surefire Scout Light® M600 and M300 series
weapon lights. It replaces the stock Picatinny rail adapter with a low
profile mount available for KeyMod and M-Lok handguards. The mount is
especially useful on handguards that feature 45 degree angle mounting
flats, such as the Bravo Company KMR, Knight's Armament URX 4, and
Geissele Automatics SMR Mk8.
When used on a 45 degree angle mounting flat, the Inline Scout®
allows the user to position the light closer or farther away from the
top 12 o'clock rail to give clearance for front sights or other
accessories. Three positions are provided, allowing an offset of
0.12" to either side of center. The base of the Surefire Scout Light®
sits 0.2" above the KeyMod or M-Lok mounting surface.
Additionally, the mount can be used in a cantilever fashion, with the
end of it protruding past the front of the handguard. This can
be useful with short handguards to help reduce barrel or suppressor
Installation tip: In order to reduce the overall length of the mount
as much as possible, it is necessary to unscrew the tail cap of the
light to access the front-most mounting screw.
Compatibility with front sights varies depending on mounting location on handguards with 45 degree flats:
1. Top left 45 degree flat: Most sights work, including MBUS Pro,
Knight's Armament Micro, Troy folding, and Diamondhead. MBUS Gen II work
if positioned to allow clearance for the release tab.
2. Top right 45 degree flat: Due to the asymmetrical body of the
Surefire Scout Light®, placement of the front sight and light are more
critical in this setup. The smaller sights like MBUS Pro and Knight's
Armament Micro work fine, but the Troy, Diamondhead, and MBUS Gen II
will not be able to clear the main body where the screw holes reside for
the stock picatinny adapter. This means one or the other will have to
be moved forward/back to get appropriate clearance. The longer battery
cavity in the M600 makes this easier since the front sight can easily
sit beside the light body in this area. Another option is to use the new
300 Series Light Body or 600 Series Light Body, which will allow plenty of clearance.
The mount is CNC machined from 6061 aluminum and type III hard coat anodized. Includes necessary screws to attach light body to mount.
