The patented Arisaka Inline Scout Mount is engineered to work with a wide range of tactical lights, including the Surefire Scout Light M600 and M300 series, Arisaka 300, 600 and 18650 Series Lights, Modlite OKW and PLH, Olight Odin, and the Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser). This mount replaces the standard Picatinny rail adapter with a low-profile M-Lok solution designed for modern handguards. The Inline Scout Mount delivers particular advantages on handguards with 45-degree angle mounting flats, such as the BCM MCMR, Geissele Automatics SMR MK4, MK8 and MK16, Daniel Defense MFR, KAC URX4, ALG Defense EMR, MI Gen 3, and Mega MML and Mega/Hodge Wedge Lock models.
When mounted on a 45-degree angle flat, the Inline Scout Mount grants flexibility to position the light closer to or farther from the top 12 o’clock rail, providing clearance for front sights and other accessories. Three mounting positions deliver an offset of 0.12″ to either side of center. The Surefire Scout Light base sits only 0.2″ above the mounting surface. To minimize overall mount length during installation, unscrew the tail cap of the light to access the front-most mounting screw. This mount is not intended for cantilever use extending beyond the end of the handguard. Compatible with the Modlite PLH, PLHv2 and OKW, Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, M612V, M622V, Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), Olight Odin, CD REIN, and Arisaka 300, 600 and 18650 Series.
