The Patent Pending Arisaka Offset Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights. It replaces the stock Picatinny rail adapter with a low profile mount for M-Lok handguards. The Offset Scout Mount is very low profile at less than 0.165" thick, and also functions perfectly with the Arisaka 300 and 600 Series Light Bodies. When used on the side mounting surfaces of an M-Lok 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 four 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. Four positions are provided, spanning approximately 0.320". 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 is compatible with most M-Lok handguards like the Geissele SMR MK4 and MK8, Mega MML and Wedge Lock, Midwest Industries SSM, Aero Precision Enhanced, EraThr3, Stubborn Mule SMLock, and SLR Rifleworks M-Lok models. Length: 1.265" Weight: 0.4 oz The mount is CNC machined from 6061 aluminum and type III hard coat anodized. Product includes mount, M-Lok nuts, and screws necessary to attach light to mount. Scout light, handguard, and any other firearms or accessories shown in above product photos are not included.
