Arisaka Defense Adjustable Offset Scout Flashlight Mount - M-LOK Compatible, Aluminum, Black

The Arisaka Defense Adjustable Offset Scout Flashlight Mount is a patented M-LOK accessory designed to mount scout-style weapon lights on modern rifle handguards with a clean, low-profile footprint. Built from aluminum and finished in black, this mount replaces the standard Picatinny rail adapter with a streamlined option that positions your light at a 45-degree angle when mounted to M-LOK slots, tucking it tighter to the rail system while keeping it out of the way of optics, front sights, and other gear. Whether you're running a dedicated low-light rifle setup, a tactical carbine, or an AR platform for home defense, this mount lets you orient your light at the 1:30, 10:30, 4:30, or 6:30 clock positions depending on your preference and dominant hand.

What sets this mount apart is its adjustability. Three lateral mounting positions span approximately 0.240 inches, giving you the flexibility to fine-tune light placement closer to or farther from your top rail, front sight, or other mounted accessories. If you're running larger or taller front sights, using the mount with Arisaka 300 or 600 Series light bodies will gain you even more clearance. At less than 0.20 inches thick, it maintains a minimal profile that doesn't add unnecessary bulk to your setup. The mount is made in the USA and ships with all necessary hardware—two M-LOK nuts, two 10-24x5/16" Torx button head screws, and two 8-32x3/8" Torx flat head screws.

Compatibility is broad across popular weapon light platforms. The mount works with Modlite PLH and PLHv2, Modlite OKW, Surefire M300 and M600 series lights, Streamlight Protac Rail Mount models, Olight Odin, and the full Arisaka 300, 600, and 18650 Series. It fits most standard M-LOK handguards including BCM MCMR, KAC URX4, and Geissele SMR variants—though some proprietary profiles like the Aero Precision Enhanced Gen 2, SIG MPX, and MCX Virtus have their own dedicated mount versions.

Frequently Asked Questions

What weapon lights are compatible with this M-LOK offset scout mount?

The mount is compatible with Modlite PLH, PLHv2, and OKW; Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, and M622 series; Streamlight Protac Rail Mount 1, 2, and HL-X (non-laser versions); Olight Odin; Cloud Defensive REIN; and Arisaka 300, 600, and 18650 Series lights.

Which M-LOK handguards work with this mount?

The mount fits most standard M-LOK handguards, including BCM MCMR, KAC URX4, and Geissele SMR MK8/14/16. It will not fit Aero Precision Enhanced Gen 2, SIG MPX, or MCX Virtus profiles—those platforms require alternative Arisaka offset mounts. Aero Precision R-One and S-One owners should use the Offset Scout Mount Galil/MPX variant, and Enhanced Gen 2 owners should use the Offset Scout Mount Spear.

How does the offset positioning improve my sight picture?

When mounted to M-LOK side slots, the light orients at a 45-degree angle and sits closer to the handguard, placing it at the 1:30, 10:30, 4:30, or 6:30 clock positions depending on your mounting orientation. This keeps the light out of the way of your optics and front sight while maintaining a clean, uncluttered upper receiver—critical for unobstructed aiming and sight alignment.

What's included in the box?

The mount comes complete with two M-LOK nuts, two 10-24x5/16" Torx button head screws, and two 8-32x3/8" Torx flat head screws, so you have everything needed for installation on your handguard.
