RGN hand grenade

The RGN hand grenade (Ruchnaya Granata Nastupatel'naya) is an offensive Russian fragmentation hand grenade. It consists of a single layered aluminium pre-fragmented body. It is very similar to the defensive RGO hand grenade. The grenade shell consists of two internally serrated aluminium hemispheres. The UDZS fuze has both impact and time delay functions, the impact fuze arms after a pyrotechnic delay of 1 to 1.8 seconds. If the grenade strikes an object after this time a spherical lead shot filled impact weight will trigger detonation. If the grenade has not struck anything after 3.2 to 4.2 seconds the second pyrotechnic delay will detonate the grenade. The grenade has a lethal radius of between 4 and 10 meters, and a safety radius of 25 meters. It can be thrown 30 to 40 meters. The grenade is in production in Russia and the Ukraine, and is in service with a number of other countries.
