Arisaka Defense Inline Scout Mount M-Lok

The Patented Arisaka Inline Scout Mount is designed specifically for the Streamlight Protac Rail Mount 1, 2 and HL-X along with Surefire Scout Light M600 and M300, the Arisaka 300 and 600 Series Lights, Modlite OKW and PLH. It replaces the stock Picatinny rail adapter with a low profile mount for M-Lok handguards.

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 0.2″ above the mounting surface.

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.

This mount is not intended for use in a cantilever fashion where it hangs off the end of the handguard.

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 Troy folding.

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.

Compatible with Modlite, Surefire M300A, M300B, M300C, M600B, M600C, M600P, M600U, M600V, M600DF, Modlite PLH and OKW, Streamlight Protac Rail Mount 1, 2 and HL-X, and Arisaka 300 and 600 Series.
