Arisaka Defense - PICATINNY, Inline-Side Scout
ISM-P
The Patent Pending Arisaka Inline Scout Mount (ISM-P) and Side Scout Mount (SSM-P) delivers a low-profile alternative to standard Picatinny rail adapters, positioning your weapon light underneath the B.E. Meyers MAWL laser/illuminator series without interference. Three adjustable positions accommodate different light head diameters for optimal clearance and ergonomics. Engineered for Z-Bolt® LEP, LED, and Infrared Illuminator Weapon Lights (Gen 2), plus leading tactical platforms including Modlite PLH/PLHv2/OKW, Surefire Scout and M-series lights, Streamlight Protac Rail Mount variants, and Arisaka 300, 600, and 18650 Series. Tactical professionals and precision shooters benefit from reduced profile, improved sight picture access, and seamless integration with modern weapon-mounted systems.
