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.
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.
