Arisaka Defense - Offset Scout Mount M-Lok

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, also functions perfectly with the Arisaka 300 and 600 Series Light Bodies.

When used on the side mounting surfaces of M-Lok handguards, the Offset Scout® Mount places the light at a 45 degree angle 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. 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 MIL-A-8625 Type III hard coat anodized. Includes necessary screws to attach light body to mount.

    Excellent part.

    If you have a Surefire scoutlight or a Streamlight Rail Mount 1,2 or Hlx 1000 lumen this is an awesome way to mount the light up close to the hand guard and to lose some of the weight of the stock mount and pic rail piece you are most likely using on you mlok hand guard. Will not work with the streamlight HLx laser. This will tighten up the profile of the gun and looks great, it’s a Durable part that won’t break.

    I have two of these, work perfectly on my Giessle mlok rail, allows me to mount the light offset while still clearing a peq15.

    Great mount

    easy to install, easy to mount the light. Used on an ALG EMR V3 which doesn't allow it to actually be offset, would've been better off with an in-line mount. Rated 4 stars because the screws to mount the light to the mount itself came loose within a few hours, even though it was tightened down completely. Used loctite so they won't budge anymore. Otherwise, great mount.
