The Arisaka Inline Scout Mount is specifically engineered to accommodate Surefire Scout Light M600 and M300 series weapon lights, Arisaka 300, 600 and 18650 series lights, Olight Odin and Streamlight Protac rail-mount 1, 2 and HL-X lights. It replaces the stock picatinny rail adapter with a low-profile mount designed for KeyMod handguards. Constructed from 7075 aluminum for exceptional strength, this mount utilizes BCM's patented inverted KeyMod screws featuring twin recoil lugs for simplified installation and a secure connection to your handguard. It is particularly effective on handguards featuring 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. When mounted on a 45 degree angle mounting flat, the Inline Scout Mount allows for precise adjustment of the light's position relative to the top 12 o'clock rail. This adjustment accommodates clearance for front sights or other accessories, offering three positions that offset 0.12 inches to either side of center. The base of the Surefire Scout Light sits only 0.2 inches above the mounting surface, ensuring a streamlined and ergonomic setup for optimal tactical performance.
