The Arisaka Side Scout Mount (SSM) is designed for use withSurefire Scout Lights, the Arisaka 300 and 600 Series, the Modlite 18350 and 18650 and the Streamlight Protac Rail Mount lights. It replaces the stock Picatinny rail adapter with a low profile mount for M-Lok handguards, and tucks the light underneath either side of the ATPIAL laser/illuminator series, including the ATPIAL-C, AN/PEQ15, and LA-5/PEQ. It will also allow the light to clear the QD lever on the Steiner DBAL I2, A3, and D2.
The SSM is compatible with the Surefire M300A, M300B, M300C, M600B, M600C, M600P, M600U, M600V, M600DF, Streamlight Protac Rail Mount 1, 2 and HL-X, Modlite 18350 and 18650 and Arisaka 300 and 600 Series.
As a bonus, the Side Scout Mount also works nicely on the Sig MPX PCC and MCX Virtus M-Lok handguards.
