Arisaka Defense Inline Scout Mount - Keymod
The Patent Pending Arisaka Inline Scout® Mount is 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® Mount 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 shadows.
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 Arisaka 300 Series Light Body or 600 Series Light Body, which will allow plenty of clearance.

Arisaka mount
I picked up the Mount as well as the 300 light. Love how close to the 12 o’clock position it is and doesn’t interfere with front sight.

Barely know its there.
It's almost like the Scout Light has Keymod mounts itself. This thing gets the light right where I want it and kicks the light out far enough to clear the Magpul Pro front sight (BCM KMR rail at 1030 mounting position).

Great scout light mount
Excellent mount, high quality with good adjustment. Better price than competitors.

Streamlined
Streamlined way to mount a Surefire scout light. I use it on a KMR handguard to mount at an angle. Much less chunky than the stock mount, but harder to remove if that matters to you. It doesn't to me.
