Arisaka Defense Offset Scout Light Mount for KeyMod Handguards, Low-Profile OSM-K

Product Description

The Arisaka Offset Scout Mount for KeyMod handguards provides a low-profile, 45-degree light placement that tucks your weapon light closer to the rail for streamlined handling. Engineered around BCM’s patented inverted KeyMod screws, the mount is less than 0.20 inches thick and offers three lateral light body positions to fine-tune clearance around front sights and other accessories. It is designed for popular lights including SureFire Scout M600/M300 series, Modlite PLH/PLHv2/OKW, Arisaka 300/600/18650 Series, Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), Olight Odin, and CD REIN. CNC machined from 6061‑T6 aluminum and finished with MIL‑A‑8625 Type III hard coat anodizing, the OSM‑K includes the required mounting hardware and is made in the USA. Note: It is compatible with most KeyMod handguards (e.g., BCM KMR, KAC URX4) and will not fit the handguard profile of the Aero Precision Enhanced Gen 2, SIG MPX, or MCX unless using the round suppressor‑width handguard.
