If you are looking for the world’s most renowned Airsoft grenade, you have found your match. The Thunder-B uses a reusable core which is combined with a single-use shell that detonates from the released high-pressure gas upon removing the pin and safety lever. If you are holding on to the pin and lever, you can reuse this grenade with a fresh plastic shell, making this an affordable and highly effective airsoft grenade that comes in handy for clearing rooms, distracting enemies behind cover, or as a tactical option on open fields.
