The Arisaka Side Scout Mount (SSM) is engineered for compatibility with Surefire Scout Lights, Modlite PLH and OKW weapon lights, Arisaka 300, 600 and 18650 series lights, Streamlight Protac rail-mount lights and Olight Odin. It replaces the conventional picatinny rail adapter with a low-profile mount designed specifically for M-LOK handguards. This configuration allows the light to be positioned beneath either side of the ATPIAL laser/illuminator series, encompassing models such as the ATPIAL-C, AN/PEQ15 and LA-5/PEQ. The mount also ensures sufficient clearance for NGAL and the QD lever on Steiner DBAL I2, A3 and D2 units.

Furthermore, the Side Scout Mount is also compatible with Sig MPX PCC and MCX Virtus M-LOK handguards, offering versatility in mounting configurations.
