Description
Hakkotsu Thunder B Shocker Sonic Grenade Fuze
This is a Hakkotsu Shocker sonic grenade fuze for the Thunder B sound grenade system. The fuze is the reusable heart of a Thunder B: it holds the CO2 capsule and the firing parts, and screws onto a shell to turn it into a working sound grenade.
Thunder B is one of the best-known sound grenade systems in airsoft and paintball, and a spare fuze is useful for any player or team who wants more than one grenade ready at the start of a game. Having a second fuze means you can prepare two grenades before going into a building, or keep one as a backup if the other is lost on the field.
Compatibility
Made for the Hakkotsu Thunder B system. You will need Thunder B shells and a 12g CO2 capsule for each use, and both are sold separately. Shells come in different styles, so check that any you buy are designed for Thunder B.
Care and maintenance
Keep the firing mechanism clean and dry, and wipe off mud and grit after each game so the pin and spoon move freely. Only fit a CO2 capsule when you are ready to use the grenade, and never leave a charged unit lying around or try to open it.
Store CO2 capsules somewhere cool and away from heat and direct sunlight. Collect every piece of a burst shell after use, both to keep the site tidy and to make sure nothing is left on the ground.
Who is it for?
This fuze is for Thunder B users who want a spare firing mechanism, and for teams and scenario players who like to carry more than one sound grenade into a game.
Please note: Shells and CO2 capsules are not included. Always wear eye protection, use hearing protection with sound grenades, and follow your site’s rules.
