The Patent Pending Arisaka Inline Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights, the Arisaka 300 and 600 Series Lights, and the Streamlight Protac Rail Mount 1 and 2. It replaces the stock Picatinny rail adapter with a low profile mount for KeyMod 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, MI Gen 3 and Mega MKM. This new version is made of 7075 aluminum for superior strength and uses BCM's patented inverted KeyMod screws with twin recoil lugs for easier installation and a solid connection to your handguard.

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 only 0.20" above the KeyMod or M-Lok mounting surface, making it the thinnest inline style mount on the market.

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. Another option is to use an Arisaka 300 Series Light Body or 600 Series Light Body, which will allow plenty of clearance.

Length: 3.0"

Height: 0.20" (at Surefire Scout Light mounting point)

Weight: 0.5 oz

The mount is CNC machined from 7075 aluminum and MIL-A-8625 Type III hard coat anodized. Includes necessary screws to attach light body to mount. Requires a T15 Torx and 5/64" Allen wrench for installation (not included). Surefire AA Scouts are not compatible because the bodies are longer and cover the mounting screws. BCM KeyMod screws are covered under US Patent 9377274. Made in the USA.

Very clean December 28, 2016
Reviewer: Terry Lomax from Bartlett, TN United States  
I have used Vltor, magpul, gg&g , The Hailey Stategic Thorntail and others. The KMR Alpha 13 inch with this at a 45 degree angle and Surefire 600  is by far the cleanest set up yet.  No need for a tape switch. You can grip the rail perfectly and  activate the light easily with you thumb. Works ambi as well. Great product!!

Great piece of gear December 28, 2016
Reviewer: J from Arlington, VA United States  
Really tucks the Scout or Protac line of lights up close on the keymod KMR rail.  Keeps the rifle streamlined.  I run this with a Protac 1L on my KMR and its fantastic!

Perfect Fit September 22, 2016
Reviewer: Andrew from Idaho  
This is my first experience with a keymod mount for a scout light. I use a gear sector mount on my  BCM EAG upper. I like the gear sector mount, but it was a tight fit with the pressure switch I run at 12:00.

The Arisaka mount provides an additional mounting hole left and right of the center line mounting holes. These additional holes allow you to offset the light either right or left of the center line holes on the mount. This was just enough room to give me perfect clearance with the pressure switch.
