Thunder B Stick Type CO2 Sound Grenade, Set with 12 Shells

The Thunder B Stick Type is a CO2-powered sound grenade shaped like a classic stick grenade with handle. The set contains one core, one handle and 12 shells, and the grenade is operated with a pull pin like the original before it goes off with a powerful bang of over 130 dB.

Thunder B is one of the most widely used sound grenade systems in airsoft because it runs on CO2 instead of powder. No pyrotechnics are involved, and the core can be reused – after use you simply change the CO2 cartridge and shell. The stick grenade shape also makes it an obvious choice for WWII scenarios and other historical themed games, where an ordinary round grenade looks wrong.

Thunder B Stick Type – key features

Key features and why they matter:

• Over 130 dB: A powerful bang that can be heard clearly in buildings and woodland, where weaker sound grenades are easily drowned out.
• CO2 without powder: No powder or pyrotechnics, so storage and handling are simpler than with pyrotechnic grenades.
• Reusable core: After use, only the CO2 cartridge and outer shell are replaced – the core and handle are used again.
• 12 shells in the set: A complete set with 12 shells covers many throws and gives a good starting point for a whole game day or a weekend event.
• Realistic stick grenade: Pull-pin operation and stick grenade shape make it well suited to historical scenarios, and the grenade can be carried in a vest or jacket.

Maintenance and safety

• Throw the grenade immediately after the pin is pulled, and keep it away from the face and ears – the bang is powerful.
• Never fill BBs, water or other objects into the grenade; it is purely a sound simulator.
• Wear eye protection, and follow the site's rules for using sound grenades and safety distances.
• Follow the supplied manual when fitting the CO2 cartridge and shell, and store the core dry and without a cartridge.
