The Offset Scout Mount uses BCM’s patented inverted KeyMod screws” which allows it to be less than 0.20″ thick. When used on the side mounting surfaces of a KeyMod handguard” the Offset Scout Mount places the light at a 45 degree angle and tucks it in closer to the handguard. Oriented upwards” the light is located at approximately the 1:30 or 10:30 clock positions. Oriented downwards” the light is located at approximately the 4:30 or 6:30 clock positions. The Offset Scout Mount also provides three lateral mounting positions for the light body” which allows the user to position the light closer or farther away from the top rail” front sights” or other accessories. Three positions are provided” spanning approximately 0.240″. When used with the Arisaka 300 Series Light Body or 600 Series Light Body” even more clearance can be gained for larger front sights.
