Stock Status:

The Arisaka Offset Scout Mount is designed specifically for the SureFire® Scout Light M600 and M300 series weapon lights, the Arisaka 300 and 600 Series Lights, and the Streamlight Protac Rail Mount 1, 2 and HL-X. 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 0.20" 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 0.240". 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 should be 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.


Length: 1.265"

Weight: 0.4 oz

    Top notch

    After some research online. I found that the Surefire scout and the Streamlight Pro tac 1 have the exact same mounting pattern after removing the picatinny mount. All the photos online show the Arisaka mount on the right side of the rail. I'm a left handed shooter but I order the Arisaka mount anyways. Most keymod products have an arrow on the bottom side showing which way is forward. This is where it shines. It's 100% ambidextrous. My Streamlight Pro tac rail mount went on the left side beautifully. This mount is fantastic. It also states which brand rails it mounts to. I put this on my Core 15 roscoe pistol. It has a larger diameter rail and fit just fine. So now I need another one.

    Best AR Light Mount

    The Arisaka setup is the only light mount I run on my ARs. It tucks a Surefire Scout in tight to the rail. When combined with the Arisaka modified Scout body, you cannot get a more compact Scout setup.

    Customer Service

    Light Mount is outstanding: customer service is poor!

    20 minutes after placing my order and not receiving an email confirmation, I called five times with no answer. I emailed to receive an immediate response only to discover my item was not scheduled to be sent to my requested delivery address. Furthermore, I was told the item had already been shipped. Untrue, the item shipped the following day.

    Great Product

    I purchased this light mount after hearing Streamlight had copied SureFire's mounting hole pattern. This mount works flawlessly with the Streamlight ProTac 2. The offset brings the light exactly where my thumb hits when I turn it on. The finish is a perfect match to my hand guard. If you're looking for a new mount, you've found it here.

    Great Mount!

    This places my scout m300 closer to the rail than any other mount i've tried. I have the Troy BUIS and it has room to spare when mounted @11:00 When mounted @1:00 it will fit in the 4th hole with a very small clearance. All in all this is a great minimalist looking mount that works great for getting things as compact as possible. Fit n finish is excellent as well. You can tell they take pride in their work.

    Arisaka Offset Scout Mount KeyMod

    Item was as described and worked well with my Surefire M600. The mount was low profile and allowed a nice clean fit.

    best keymod scout mount available!

    This mount is great. It keeps my scout light as close to the handguard as possible, making for a very low profile. Thanks BCM.
