ARISAKA OFFSET SCOUT MOUNT M-LOK

Description

The Arisaka Defense Offset Scout Mount is built for shooters who run a SureFire Scout M300 or M600, a Modlite PLH or OKW, an Arisaka 300 or 600 Series light body, or a Streamlight ProTac Rail Mount 1, 2, or HL-X on an M-LOK handguard and want to ditch the bulk of a standard Picatinny adapter. Rather than stacking the light on top of a thick riser, the OSM-M sits at less than 0.165 inches thick, dropping the light body as close to the handguard surface as practically possible and keeping the overall package compact.

Installed on the side of a handguard, the mount cants the light to 45 degrees. Oriented with the bezel upward, the head ends up near the 1:30 or 10:30 position; flipped downward, it sits at roughly 4:30 or 6:30. That offset geometry pulls the light body inward toward the rail system rather than letting it protrude outward, which helps preserve clearance for sling attachment points and reduces the profile presented at barriers.

Four lateral mounting positions span approximately 0.320 inches of adjustment, letting you walk the light closer to or farther from the muzzle end relative to the front sight or other accessories. When paired with the Arisaka 300 or 600 Series light body specifically, additional clearance over taller front sights becomes available — a practical consideration on rifles where the iron sights sit high. The mount is machined from 6061-T6 aluminum and finished in MIL-A-8625 Type III hard coat anodize. Installation requires T25 and T20 Torx wrenches, which are not included. Manufactured in the USA.
