Arisaka Defense Side Scout Mount (SSM), M-Lok

The Arisaka Side Scout Mount (SSM) is designed for use with Surefire Scout Lights, the Arisaka 300 and 600 Series, 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 locking 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, and Arisaka 300 and 600 Series.

Length: 1.265"

Thickness: 0.2"

Weight: 0.6 oz

The mount is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Includes necessary screws to attach light body to mount. Requires a 3/32" and 1/8" Allen wrench for installation (not included). A T9 Torx driver is required to remove the stock Picatinny mount from Surefire Scout Lights.

    Side scout mount is awesome

    I like my light on the left side of my rifle so with the law tactical folder all the bulk is on on the left and my d bal lever can clear so now I can comfortably run just the light with click cap or light and Lazer via pressure pad

    Great piece of kit

    This mount works perfectly with a Surefire M600 and the AN/PEQ-15 laser. The light fits very close so it keeps potential snags down to a minimum.
