The Patent-Pending FireTail is an advanced weapon light activation device that enhances the ergonomics by changing the direction of pressure to activate your light. By attaching a FireTail to the tailcap of a 1″ diameter tactical flashlight, you gain the ability to activate your flashlight with a less awkward, more ergonomic lateral squeeze motion. Laterally applied pressure (squeezing) is a more intuitive, natural motion for support-hand activation. FireTail doesn't modify the functionality of your rifle-mounted flashlight, it merely changes the direction of pressure required for activation.
