This Dual Rail Accessory Platform comes with a bracket already installed on one of the rails for the M-3/M-6 family of lights and allows you to pick any of our other Belt-clip mounted accessories and place them alongside on one of these platforms. If you don’t want the M-3 holder, simply remove it and mount another accessory of your choice. Available in both paddle and belt loop models, these Dual Rail Accessory Platforms are another example of how BLACKHAWK! CQC gives you choices.
