The Arisaka Side Scout Mount M-LOK is a purpose-built offset light mount designed to integrate scout-style weapon lights cleanly with M-LOK handguards. If you're running a rifle with a modern M-LOK rail system and want to mount a SureFire, Streamlight, or Arisaka scout light without the clunk and bulk of a traditional Picatinny adapter, this mount tucks the light under the handguard for a streamlined, lower-profile setup that doesn't interfere with your sight picture or handling.

Built from 6061-T6 aluminum and CNC-machined for precision fit, the Side Scout Mount positions your light to clear common optic systems—including ATPIAL laser setups and Steiner DBAL models—so you're not fighting conflicting hardware on your rail. It works with longer-base lights like the M620, M961, and M962 when paired with the Arisaka Offset M620 adapter. Installation is straightforward, requiring only a 1/8-inch Allen wrench and T20 Torx driver.

This mount has earned solid real-world use on both dedicated rifle platforms and pistol-caliber carbines, particularly SIG Sauer MPX and MCX variants. Whether you're building a tactical carbine, a duty rifle, or a home-defense setup, the Arisaka Side Scout Mount delivers the offset versatility that modern shooters expect without the compromise in ergonomics or aesthetics.
