Arisaka Defense Offset Scout KeyMod Mount Black. It replaces the stock Picatinny rail adapter with a low profile mount for KeyMod handguards. The Offset Scout Mount uses BCM's patented inverted KeyMod screws which allows it to be less than 0.20in 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 0.240in. When used with the Arisaka 300 Series Light Body or 600 Series Light Body even more clearance can be gained for larger front sights. As shown in the pictures the Offset Scout Mount fits the Noveske NSR perfectly and is compatible with most KeyMod handguards like the BCM KMR KAC URX4 Geissele SMR MK4/5 KeyMod Mega MKM Midwest Industries SSK and Daniel Defense SLiM. Compatible with Surefire M300A M300B M300C M600B M600C M600P M600U M600V M600DF Streamlight Protac Rail Mount 1 2 and HL-X and Arisaka 300 and 600 Series. M620 series lights can also be used with the Offset Scout Mount with the addition of the Arisaka Offset M620 Adapter. 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.
