Arisaka Light Mount Features The Arisaka Defense Light Mount replaces the OEM Picatinny mount on Surefire Scout Light Pro swivel bodies fitting models including the M140A M340C M340V M640DF M640U and M640V. Its patent-pending inline design positions the light for optimal use alongside lasers avoiding interference between accessories mounted on the same rail. The mount can also be installed in a cantilever position off the end of the handguard pushing the light further forward to reduce barrel or suppressor shadow on target. This flexibility lets shooters tune light placement to their specific rifle configuration. A triangular cross-section gives the mount resistance to twisting or bending forces that a standard rectangular mount might not withstand under hard use. Two 10-32 by 1.25 inch Torx cap head screws secure the mount in place and the anodized black finish matches most rifle hardware. At just 3 inches long and 1.7 ounces the mount adds minimal bulk or weight to a weapon light setup. Made in the USA the Arisaka Defense Light Mount is built for shooters who want a stronger more adaptable mounting option for their Surefire Scout Light Pro.
