The Arisaka Defense Inline Scout Mount (brand part no. ISM-P) is a patented weapon light mount, not itself a light or laser, built for Picatinny rails. It replaces the stock Picatinny rail adapter with a low-profile mount that tucks the light close to the bore line, built for use with Surefire Scout Lights, Modlite PLH and OKW, Arisaka’s own 300, 600, and 18650 Series lights, and the Streamlight ProTac Rail Mount line.
