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.

Great shipping. Came faster then anticipated. Exactly as advertised. Will shop here again.
I have many arisaka mounts. This is my first inline mount but it works perfect for my MCX
I picked this mount carefully to mount a M600V on an ALG V3 rail under an ATPIAL-c. It fits perfectly and is a fraction of the cost of some of the specialty light mounts meant to work with the PEQ-15 family of lasers.
The Arisaka Defense Inline Scout Mount - M-Lok works well for the purpose it is intended. Expensive, but does the job well.
Shipping was top notch. Recived product very quick. Product is great quality. For my setup I had to remove the handguard to install. The offset mount would have been a lot quicker and easier.
Perfect for mounting a Surefire Scout light to a Geissele SMR MK8 M-LOK rail top 45 degree face. Very low profile and rigid mounting solution. Also has capability to move light body left or right on mount to clear front sight/laser/etc. Very easy to install. 4/5 stars for not having nylon patches on screws as Magpul products have. Needs some loc-tite.
The Arisaka in-line mount is solid, and keeps your light close into the rail. Very low profile. Very light weight.
This mount is awesome, my m600v hugs the rail so close and seamlessly thanks to this awesome piece of kit.
Having run an Arisaka offset Keymod mount for a year or so now there was no doubt they make a solid product. My only quip about this particular M-Lok setup is needing to remove the tailcap of the flashlight to mount it on a rail but that's an incredibly minor nuisance.
