Bust A Cap is a new device that attaches to the end of your existing flashlight or baton to give you a tactical advantage to break glass. This rapid entry tool was designed by a 13-year police veteran to provide safe entry or exit out of an automobile, house, boat, or plane. Bust A Cap is manufactured in the United States. It is made from special steel, can be applied in less than a minute, requires no training, and will break glass with one tap. Models are available to fit many flashlights and batons.
