Here is a dart launcher that you can use for hunting or self defense. This Ballistic Dart Gun can fire stainless steel darts with high accuracy range of 16 feet. The darts can reach a distance of 30ft. The protective collar acts as safety, so you can’t fire unless pulled down.
To use the device, remove the safety cover, pull down the collar, and press one of the buttons to launch a dart. This self defense tool costs under $30 at this time.
