Arisaka Defense Offset Scout Mount – M-LOK


Flat Dark Earth (FDE)

Product Description

The Patent Pending Arisaka Offset Scout Mount is designed specifically for the SureFire Scout Light M600 and M300 series weapon lights, the Modlite PLHv2 and OKW weapon lights, the Arisaka 300 and 600 Series Lights, the Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), and Olight Odin. 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 0.20″ thick.

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 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 is compatible with most M-Lok handguards like the BCM MCMR, Geissele SMR MK4, MK8, MK13, MK14, MK16, Mega MML and Wedge Lock, Midwest Industries SSM, EraThr3, SMOS, and SLR Rifleworks M-Lok models.

Compatible with the Modlite PLH and OKW, Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, M612V, M622V, Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), Olight Odin, and Arisaka 300 and 600 Series.

Best Prices; Fast Shipping; Excellent Product

Mil Spec retail had the best price on the Arisaka Offset Mount, even after adding on the cost of shipping. They got me the mount fast and included a free sticker too. As with all Arisaka products, the mount was of the highest quality.

Buy it now or buy it later

No question this costs more than inferior options, but you get what you pay for. The machining is impeccable and this is simply the best mount for Sure Fire and Streamlight weapon lights on the market. It fits tight to the rail, and allows for a little flexibility with multiple mounting locations. Milspec Retail ships fast, ships free, and their customer service is top notch!

One of the best sount mounts

Arisaka makes one of the best scout mounts in the game. I paired this with my modlite and it sits perfectly since they give you the option to adjust how far/close you want the weapon light to the rail. Great product would buy again!
