The Patented Arisaka Inline Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights, the Arisaka 300, 600 and 18650 Series, Olight Odin, and the Streamlight Protac Rail Mount 1, 2 and HL-X. It replaces the stock Picatinny rail adapter with a low profile mount for KeyMod handguards. The mount is especially useful on handguards that feature 45 degree angle mounting flats, such as the Bravo Company KMR, Daniel Defense MFR, Knight's Armament URX 4, MI Gen 3 and Mega MKM. This version is made of 7075 aluminum for superior strength and uses BCM's patented inverted KeyMod screws with twin recoil lugs for easier installation and a solid connection to your handguard.
