Designed especially for the M300 and M600 Surefire Scout lights, the Arisaka Offset Scout Mount for KeyMod is perfect for mounting a light at the 45-degree position. The mount is also compatible with the Arisaka 300 and 600 series lights as well as the Streamlight Protac Rail Mount 1, 2, and HL-X lights. The mount replaces the factory Picatinny adaptor with a low profile offset mounting option. The Arisaka Offset Scout Mount uses BMC's patented inverted KeyMod screws to keep the mount to a very manageable 0.20" thick.
