The Red Lightning Rail with GripSense offers a seamless integration of advanced laser activation technology for firearms. With its sleek black finish this laser sight is designed for universal firearm compatibility ensuring versatility across various models. The innovative GripSense technology allows for effortless and intuitive activation by simply gripping the firearm without altering your natural firing stance. Featuring a clear red laser with a wavelength of 650nM the device projects a precise 0.63-inch dot at 20 yards reaching a range of up to 50 meters. The laser mounts easily onto a Picatinny rail or trigger guard making it a convenient addition for pistols with at least one inch of rail space. Weighing just one ounce it provides up to twenty hours of battery life thanks to its 1/3N battery and includes a ten-minute timeout feature to prevent accidental power drain.
