Description: The grenade consists of two metal shells pressed together and sealed. The upper shell contains a Bouchon igniter and a delay fuse. The bottom shell contains the illuminant composition, first fire charge, ignition charge, quick match, and disc. |
|
Operation: Pull the release pin and throw the grenade. When the lever is released, the firing pin is freed to fire the primer. The primer ignites the delay fuse, which burns for seven seconds and then ignites the ignition charge. The ignition charge sets off the first fire composition. The gases from the ignition charge and first fire force the two shells apart, thus leaving the illuminant composition of the bottom shell free for burning. |
