The Arisaka Dual Side Scout Mount (DSSM) has the ability to mount two Scout lights side by side and only occupies a single M-Lok slot. This mount allows the user to run a powerful white light like the 18350/18650 Series E2XTL or Modlite PLHv2/OKW, plus a supplemental infrared illuminator like the B.E. Meyers Kiji, Malkoff EX IR, or Modlite IR heads.

The DSSM is designed for use with Surefire Scout Lights, the Modlite IR, PLH and OKW weapon lights, the Arisaka 300, 600, 18350 and 18650 Series, the Streamlight Protac Rail Mount lightsand the Olight Odin. 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.

Compatible with the Modlite IR, 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.

As a bonus, the Dual Side Scout Mount also works nicely on the Sig MPX PCC and MCX Virtus M-Lok handguards.

    Really clean solution to mount a dedicated white light and illuminator on a single mount.
