The Arisaka Defense Inline Scout Mount (brand part no. ISM-M-FDE) is a patented weapon light mount, not itself a light or laser, built for M-LOK handguards in FDE. It replaces the stock Picatinny rail adapter with a low-profile mount that tucks the light in line with the bore, built to run the Surefire Scout Light M600 and M300 series, Arisaka’s own 300, 600, and 18650 Series lights, Modlite OKW and PLH, the Olight Odin, and the Streamlight ProTac Rail Mount 1/2/HL-X (non-laser).
