Arisaka Offset Scout Mount for MCX M-LOK - Flat Dark Earth (FDE)

The Arisaka Offset Scout Mount for MCX M-LOK is a low-profile weapon light mount engineered for shooters running modern modular handguards. If you're mounting a scout-style light on an M-LOK equipped rifle and want your optics and accessories to coexist without compromise, this is the mount that solves the clearance puzzle most competitors ignore. Arisaka's patented 45-degree offset design places your light at the 1:30 or 10:30 position (upright) or 4:30 or 6:30 (inverted), tucking it tight to the handguard rail while keeping the beam effective and your sightline uncluttered.

Built from 6061-T651 aluminum and hard coat anodized to military spec, the M-LOK version measures just 1.265 inches long and weighs a mere 0.4 ounces—minimal material, maximum function. Three lateral mounting positions let you dial in exactly how close the light sits to your top rail, front sight, or NGAL/PEQ laser. That adjustability matters: it's the difference between a light that plays nice with modern accessory stacks and one that forces you to choose between illumination and targeting lasers.

This mount is compatible with a wide range of popular scout-style lights, including Surefire Scout models (M300 and M600 series), Modlite PLH and OKW, Streamlight HL-X, Olight Odin, and Arisaka's own 300 and 600 series bodies. The M-LOK variant fits standard handguards like the BCM MCMR, KAC URX4, and Geissele SMR MK8/14/16—though note it won't work with the Aero Precision Enhanced Gen 2 or SIG MCX Virtus (unless you're using the MCX suppressor-width handguard). Installation requires an IP20 TorxPlus driver and medium-strength threadlocker; Arisaka includes the necessary mounting hardware.

Made in the USA and backed by U.S. patents, this mount represents the kind of thoughtful design that separates purpose-built gear from one-size-fits-all compromises. If you've ever fought with a rail-mounted light that interferes with your irons or laser, you'll appreciate what Arisaka solved here.

Will this mount work on my MCX Virtus handguard?

What handguards are confirmed compatible?

The Arisaka M-LOK Offset Scout Mount is designed to fit standard M-LOK handguards including the BCM MCMR, KAC URX4, and Geissele SMR MK8/14/16. It will not fit Aero Precision Enhanced Gen 2, SIG MPX, or MCX Virtus (unless using the suppressor-width variant).

What tools and installation items do I need?

You'll need an IP20 TorxPlus driver to install the mount (not included). Arisaka supplies the necessary mounting hardware. Medium-strength threadlocker (such as Loctite 222 or 243) is recommended for installation, with a suggested torque of 20 inch lbs for the M-LOK screws and light body screws.
