Modlite Arisaka Defense Inline Scout Mount Picatinny - Black - The Patent Pending Arisaka Inline Scout Mount (ISM) is designed for use specifically for lights that utilize the Scout-style mounting platform. It replaces the stock Picatinny rail adapter with a low profile mount that tucks the light underneath either side of the B.E. Meyers MAWL laser/illuminator series. Three positions on the mount allow for different diameter light heads to clear the MAWL without interference. Compatible with the Modlite 183560 and 18650 bodies/lights, Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, M612V, M622V, Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), CD REIN, and Arisaka 300 and 600 Series. 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 an IP27/T27 and IP20/T20 Torx driver for installation (not included). A T9 Torx driver is required to remove the stock Picatinny mount from Surefire Scout Lights.
