Great mount by Mark, January 23, 2020
I've used with with my Streamlight ProTac HL-X and it has worked fantastic. The offset mount is low-profile and sticks close to the rail, so there's no worry of it being snagged on anything. It holds on pretty tight to any M-LOK slots.

Great design by Matt, Verified Owner, August 30, 2024

Product Info for Arisaka Defense Offset Scout M-LOK Mounts

The Patent Pending 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 M-Lok handguards. The Offset Scout Mount is very low profile at less than 0.20in thick.image

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 0.240in. 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 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.

The mount is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Includes necessary screws to attach light body to mount. Requires a 5/64in and 1/8in Allen wrench for installation (not included). Made in specialized factories.
