Geonox Airsoft checks out one of the recently released grenades for airsoft use, the Storm Apocalypse... "In this video I show you the Storm Apocalypse. This is a reusable airsoft impact grenade. You need airsoft gas and BBs for this. A total of 155 BBs fit in. A highlight: You don't need a cotter pin. There is an on and off slider. This way you can secure the grenade for transport and arm it just before use. The effective circle has a radius of 5m. And if that grenade goes off next to an enemy, they'll definitely notice."
