This Patented Arisaka Offset Scout Mount is designed specifically for the IWI Galil ACE Gen 2 and SIG MPX M-Lok handguard profiles. Surefire Scout and Scout clones attach directly to the mount, including the Surefire Scout Light M600 and M300 series weapon lights, the Modlite PLH and OKW weapon lights, the Arisaka 300" 600" and 18650 Series Lights, the Streamlight Protac Rail Mount 1" 2 and HL-X (non-laser), and Olight Odin. When used on the side mounting surfaces of the Galil ACE Gen 2 and SIG MPX M-Lok handguards, the Offset Scout Mount places the light at a 30 degree angle to properly match the handguard, and tucks it in closer to the rail system. Oriented upwards, the light is located at approximately the 1:30 or 10:30 clock positions. This mount also works well with the Aero Precision Atlas R-One and S-One handguards. 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".
