The Spectrum Dart Launcher is a fully functional reproduction of a covert tool produced in the 1970's, now with a custom anodized spectrum finish! To fire each dart, remove the top safety cover and pull down the protective collar. Press each button to unleash the 440C stainless anodized dart above it. To reload this device, place the darts back in and put most of your body weight on the rear of the device until they lock into place. Each dart is constructed of a solid piece of 440C stainless steel, & includes 3 extra darts. Accurate at 20 feet but has no problems reaching 30+ feet. The protective collar acts as a "safety" and will not fire unless pulled down.
