Vertical fore grips are often called upon to mount pressure switches for lasers and tactical lights. In the past, Velcro or adhesive tape were less- than satisfactory methods of securing the pressure switch to the grip. Heat, rapid movement and heavy gloves often rip the switch loose with obvious consequences. The Tango grip features a novel pocket that appears when needed, to positively mount pressure switches without movement or damage. Just remove the threaded end cap, slide out the filler panel and place inside the grip for storage. Just replace the panel with your pressure switch and replace the end cap to lock the switch in place. Quick and easy, allowing fast mount and dismount of lights and lasers.
