Mounting a weapon light to a standard MIL-STD-1913 Picatinny rail with stock hardware often pushes the light body out too far. This unnecessary overhang causes snag hazards on obstacles, throws off your rifle's balance, and leaves awkward gaps that mess up thumb placement around remote switches.

The Arisaka Defense Offset Scout Mount Picatinny (OSM-P) solves rail clearance issues with functional precision. By canting your Scout-style light at a tight 45-degree angle, this mount tucks the light head directly into the recessed pockets along the 1 o'clock or 11 o'clock positions. Featuring three distinct lateral mounting positions, the OSM-P allows you to shift the light closer to or further from top-rail IR laser designator boxes like the PEQ-15, DBAL, or NGAL for a completely integrated front-end layout.

Key Features & Benefits

• 45-Degree Low-Profile Stance: Positions your weapon light tightly against the top rail, removing outer bulk for superior maneuverability through barriers.
• 3-Position Lateral Clearance: Provides 0.17" of side-to-side adjustability to fine-tune spacing around wide laser illuminators or front sight posts.
• 7075-T6 Billet Aluminum: Machined from ultra-strong 7075-T6 aluminum rather than soft 6061 metal, ensuring your light stays locked under harsh recoil and heavy impact.
• Scout Pattern Versatility: Fits Surefire Scout Light series, Modlite PLHv2/OKW, Streamlight Protac HL-X, and Arisaka Light Bodies directly without bulky adapters.
• MIL-A-8625 Type III Hardcoat: Durable matte anodized surface resists scratches, chemical corrosion, and tough field environments.
