Product Description

The Patented Arisaka Offset Scout Mount is designed specifically for the Surefire Scout Light M600 and M300 series weapon lights, the Modlite PLH and OKW weapon lights, the Arisaka 300, 600 and 18650 Series, the Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), and Olight Odin. It replaces the stock Picatinny rail adapter with a low profile mount for the SIG MCX Virtus M-Lok handguards. Please note: this mount is designed specifically for the standard MCX handguard which has a tall profile with flat sides. If you have the MCX suppressor compliant handguard you should use Arisaka's normal Offset Scout Mount M-Lok. And if you are running a top rail mounted laser like an LA-5, PEQ-15, NGAL, or DBAL, you should use Arisaka's Side Scout Mount MCX. The Offset Scout Mount MCX orients the light at a 45 degree angle and tucks it in closer to the top rail at the 1:30 or 10:30 clock positions. It also provides three lateral mounting positions for the light body, which allows the user to position the light closer or farther away from the top rail, front sights, or other accessories. Three positions are provided, spanning approximately 0.240". When used with the Arisaka 300 Series Light Body or 600 Series Light Body, even more clearance can be gained for larger front sights. Compatible with the Modlite PLH, PLHv2 and 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.
