The Midtech Dart Launcher V2 is a huge upgrade to our original! Featuring a slimmer & lighter pocket design, and an extra 2 slots making a total of 5 darts launched at the same time. The midtech dart launcher V2 is an upgrade to the fully functional reproduction of a covert tool produced in the 1970's. To fire each dart, remove the top safety cover and pull down the protective collar. Press each button to unleash the ballistic 440C stainless dart above it. To reload this device, put 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 5 extra darts (total of 10.) 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.
