Arisaka Offset Scout Mount – SPEAR


Flat Dark Earth (FDE)

Product Summary

Detailed Description

The Patented Arisaka Offset Scout Mount is designed specifically for the MCX Spear LT handguard, and is intended to be used with the Surefire Scout Light M600 and M300 series weapon lights, the Modlite PLH and OKW weapon lights, the Arisaka 300, 600 and 18650 Series Lights, the Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), and Olight Odin. It replaces the stock Picatinny rail adapter, reducing bulk and bringing the light in closer to the handguard.

If mounted at the 3 or 9 o’clock m-lok slots, the mount closely hugs the handguard while also providing enough clearance for top rail mounted lasers like the ATPIAL-C, PEQ-15, DBAL-A2, and NGAL. The mount functions with the MAWL by flipping it over and attaching it to the angled m-lok slots, with the light sitting below. This mount also works well with the Aero Precision Enhanced Gen 2 handguards.

The Offset Scout Mount 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″. This allows for use next to most laser aiming devices.

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 and Odin Mini, CD REIN, and Arisaka 300, 600 and 18650 Series.

M620, M951/2 and M961/2 series lights can also be used with the Offset Scout Mount with the addition of the Arisaka Offset M620 Adapter.
