Arisaka Defense
The Arisaka Side Scout Mount is a purpose-built rail adapter that solves a real problem for AR and tactical rifle builders: keeping your weapon light low-profile and properly positioned without compromising rail real estate. Designed specifically for scout-style tactical lights, this Picatinny mount lets you mount SureFire, Streamlight, and Arisaka weapon lights to the side of your handguard—creating a cleaner, more streamlined setup than traditional top-rail adapters.
Built from 6061-T6 aluminum and CNC-machined for precision fit, the Side Scout Mount works on M-LOK, KeyMod, and Picatinny handguards, and is also compatible with SIG Sauer MPX and MCX platforms. The offset placement tucks your light under either side of the rail, allowing it to clear quick-detach levers on Steiner DBAL I2, A3, and D2 laser systems—a feature that matters if you're running a combined optics package. Installation is straightforward: you'll need only a 1/8-inch Allen wrench and a T20 Torx driver.
Compatibility spans a wide range of popular lights, including the SureFire M300 and M600 series in all their variants, Streamlight Protac Rail Mount models 1, 2, and HL-X, and Arisaka's own 300 and 600 series. If you're using longer-base lights like the M620 or M961/2, pair this mount with the Arisaka Offset M620 adapter for optimal clearance and mounting geometry.
