This remote pressure switch and Picatinny mount are engineered specifically for attaching and controlling the Powertac M5 or Flexbeam Flashlights on a Picatinny rail (flashlight sold separately). The momentary switch activates the flashlight in its current mode and is compatible with most rifles and shotguns, excluding pump-action models. The kit includes a durable Picatinny rail weapon mount and is designed to fit within a foregrip's integrated pressure switch pocket. Alternatively, the switch can be secured using hook-and-loop fasteners or 3M VHB double-sided tape for versatile mounting options on firearms without an integrated pocket.
