Arisaka Defense - Offset Scout Mount Keymod

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 KeyMod handguards. The Offset Scout® Mount uses BCM's patent pending inverted screws, which allows it to be less than 0.165" 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 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 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 Aero Precision Enhanced KeyMod handguard.

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.

    Great mount

    It's compact and well made and goes on rock solid. Although its made for a surefire scout, it fit my streamlight perfectly. It also has multiple mounting holes for the light to allow for micro-adjustments. This feature allowed me to have enough clearance to clear the folding front sight latch. This is an all around great product.

    ...Like your mom. Works with the streamlight protac lights perfectly, durable, fit and finish are tough and attractive. Been using them on every one of my keymod equipped rifles since they became available, and they are still all functional. To my knowledge there is no better low profile mount on the market at any price.
