The Patented Arisaka Offset Scout Mount is meticulously engineered for compatibility with a wide range of lighting solutions including Surefire Scout Light M600 and M300 series, Modlite PLH and OKW, Arisaka 300, 600 and 18650 series, Streamlight Protac rail-mount 1, 2 and HL-X (non-laser) and Olight Odin. It replaces the original picatinny rail adapter with a streamlined mount designed specifically for Sig MCX Virtus M-LOK handguards. The Offset Scout Mount MCX positions the light at a 45 degree angle, snugly tucked closer to the top rail at either the 1:30 or 10:30 clock positions. It offers three lateral mounting positions for precise adjustment of the light body, allowing users to position it closer or farther from the top rail, front sights or other accessories. These positions span approximately 0.240 inches for versatile customization. When combined with the Arisaka 300 series Light Body or 600 series Light Body, the mount provides additional clearance ideal for accommodating larger front sights. Compatible with a comprehensive array of lights including Modlite PLH, PLHv2, OKW, Surefire M300A, M300B, M300C, M300V, M312, M322, M312V, M313V, M322V, M600B, M600C, M600P, M600U, M600V, M600DF, M612, M622, M603V, M612V, M622V, Streamlight Protac rail-mount 1, 2 and HL-X (non-laser), Olight Odin, CD REIN and Arisaka 300, 600 and 18650 series lights. For M620, M951/2 and M961/2 series lights, compatibility is achieved with the addition of the Arisaka Offset M620 Adapter.
