The Arisaka Patented Offset Scout Mount is engineered specifically for the SIG Sauer MCX Spear LT M-LOK handguard. This component facilitates precise integration of various weapon lights, including the Surefire Scout Light M600 and M300 series, Modlite PLH and OKW, Arisaka 300/600/18650 Series, Streamlight Protac Rail Mount 1/2/HL-X (non-laser), and Olight Odin models.
Key Features
Optimized Light Integration
- Reduced Profile: This mount replaces the factory Picatinny rail adapter, thereby reducing the overall weapon light profile. This design minimizes bulk and positions the weapon light in close proximity to the handguard, providing a compact integration crucial for operational efficiency and personal defense firearm configurations.
- Laser Clearance: When installed in the 3 or 9 o’clock M-LOK slots, the mount’s geometry ensures sufficient clearance for top-rail mounted tactical aiming devices such as ATPIAL-C, PEQ-15, DBAL-A2, and NGAL. Additionally, it maintains functionality with the MAWL when configured for attachment to angled M-LOK slots, strategically positioning the light below the laser unit.
- Adjustable Positioning: The mount incorporates three distinct lateral mounting positions for the weapon light body, allowing for a total span of approximately 0.240 inches. This precision adjustment capability enables users to fine-tune light placement relative to the top rail, front sights, or other mounted firearm accessories, supporting diverse operational requirements.
- Broad System Compatibility: Beyond its primary application with the SIG Sauer MCX Spear LT, this mount also integrates effectively with Aero Precision Enhanced Gen 2 handguards, expanding its utility across compatible platforms.
