The Arisaka Inline Scout Mount makes replacing the clumsy Picatinny mount on your Surefire M300 or M600, Arisaka 300 and 600 series lights, and Streamlight Protac Rail Mount 1 and 2 lights a snap. The Inline Scout Mount uses the factory attachment points on the light body and keeps the light body only 0.2" above the mounting surface for the tightest possible fit. Arisaka also built a side to side adjustment of up to 0.12" from center to help you clear other accessories and get the light into the most optimal position possible.
