A toy grenade, designed for launching large numbers of plastic BBs at once, consists of a cylindrical shell with an O-ring interface. The cylindrical shell has circumferentially angled guide portions that allow the O-ring to flex inwardly when moved towards the remote ends. As a result, users can safely unload all the BBs if they wish to do so.

A diversionary device trigger mechanism is provided that can be repeatedly used, and which allows a primer or blank to be discharged in two different ways. The device includes a main body with a number of other components secured to the main body about an upper chamber and a lower chamber. A firing pin, a ball bearing, an anvil, a top retaining cap, and a plunger are secured about the upper chamber. A blank carrier, a primer or blank, and a carrier receiver are secured about the lower chamber. In the first way, the ball bearing can be displaced relative to the main body, such as by throwing the device towards a surface. In the second way, the plunger can be pushed down relative to the main body. If either of these occur, the firing pin to be moved downwardly to pierce and set off the primer or blank.

A peripheral device that is used with a mixed reality system that is thrown by the user of the mixed reality system and captures scene and mapping data of the area the peripheral is thrown into. Upon capturing the scene and mapping data, the peripheral transmits the data (in some embodiments, including processed results of evaluation of the data) to the mixed reality system. The mixed reality system displays a visual representation of the scene and mapping data on a near eye display. In some embodiments, the visual representation appears in real space enabling an effect where the user of the mixed reality system can see through walls or other obstructions. In some embodiments, the peripheral is configured to detonate upon the satisfaction of a variable set of conditions.

A grenade firing mechanism 12 has a body 18 defining an internal chamber 32 in which a firing pin structure 40 is located. The firing pin structure is actuated by an inertia toggle 64 having a first end contained within the chamber and a second end region 72 which projects from the body. A safety lever 16 is releasably mounted to the second end region 72 of the inertia toggle in an operative position to prevent the inertia toggle moving to actuate the firing pin structure. A lever spring 104 is operative to eject the lever from the inertia toggle allow the firing pin structure to be actuated when the grenade is deployed. The lever 16 carries an abutment pin 120 which extends through the body to engage the firing pin structure 40 to inhibit the firing pin structure moving in a firing direction when the lever is in its operative position. The inertia toggle may have a convex abutment surface which engages the firing pin structure. The firing mechanism is particularly suited to a sound flash distraction grenade.

An electronic dazzling element has at least one optical emitter for emitting light pulses, which contains an electronic light-emitting device for generating light pulses, and a control device for controlling the light-emitting device of the optical emitter. In order to reduce the brightness reduction of the light pulses as a distance from the dazzling element increases, the optical emitter is configured to emit a collimated light beam. In order to simultaneously achieve the dazzling effect in as large a spatial region as possible, a beam direction of the collimated light beam may be changed.
