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.

In some examples, a charge holder for a grenade has an envelope made from one or more layers of a sheet material to define an interior volume to receive a charge having a charge volume less than or equal to the interior volume and a neck configured to connect to a flashbang grenade body, wherein a ratio of a charge volume of the interior volume to an envelope material volume is about 5.0 or greater.

The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.

A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a tiring pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and tire safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When, the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the -safety interlock (92) is in the firing position, actuation of the firing pin is enabled.

Primer adapter assemblies have a body having a cylindrical exterior sidewall adapted to be closely received in a chamber having a chamber diameter, the body defining a central passage including a cylindrical aft portion adapted to closely receive a primer having a primer diameter greater than or equal to the chamber diameter, the body having an aft surface, and a malleable skirt extending aft of the aft surface and defining an installation aperture, the malleable skirt being operable to deform inward to form an opening having a diameter less than the primer diameter, such that a primer in the cylindrical aft portion of the central passage is retained. The skirt may have a tapered cross-section. The skirt may encircle the central passage. The skirt may be concentric with the central passage. The body may include a flange defining the aft surface and having a diameter greater than the chamber diameter.
