Abstract: Stun grenades may include a fuze configured to ignite a delay material secured to a housing including a delay chamber in which the delay material is located. A handle of the fuze may be located over a final payload chamber of the series of payload chambers, payload material in the final payload chamber being configured to ignite after ignition of payload material in each other payload chamber of a series of payload chambers. Methods of assembling stun grenades may involve positioning an obstruction in a port extending between a delay chamber and a payload chamber of a series of payload chambers surrounding the delay chamber in a housing. A delay material may be packed in the delay chamber. The obstruction may be removed, and a payload material may be positioned in the payload chamber and the port.

Abstract: A projectile having a reactive material disposed therein is provided. The projectile includes a housing which defines a cavity, the cavity being open at one end of thereof. A reactive material is disposed within the cavity. A tip is coupled with the housing and substantially encloses the opening of the cavity. The housing, the reactive material and the tip are cooperatively positioned and configured so as to define a void space between a surface of the tip and a surface of the reactive material. Upon impact with a target, the tip of the projectile is designed to become displaced within the cavity until it contacts the reactive material and transfers kinetic energy thereto, thereby causing ignition of the reactive material. The void space may be defined to provide a desired amount of time between initial impact of the projectile with a target and the subsequent ignition of the reactive material.
