Our take: What is the scariest sound on an airsoft field? Answer: a Hakkotsu Thunder B CO2 sound grenade exploding right next to you! The Hakkotsu Thunder B Sound Grenade is one of the loudest, and easiest to use airsoft sound grenades on the market. The sound level of a Thunder B grenade explosion is 130db, which is equivalent to a loud commercial jet flying overhead! When these grenades explode, there is no mistaking the sound. These grenades are great for airsoft battles due to their ease of use, compact shape, and extreme durability. A great feature of the Thunder B CO2 Sound Grenades is their realistic firing mechanism with a fully functional grenade spoon and pin. The Thunder B cores are crafted of lightweight and durable CNC Aluminum, and can easily withstand the heavy stress of an airsoft game.

The grenade has three main components; the core and firing (puncturing) pin, a 12g CO2 cartridge (not included), and the hard plastic outer shell. When the grenade pin is pulled, and the grenade spoon/ handle is let go, the pin punctures the CO2 cartridge. The cartridge then releases its gas into the chamber of the hard plastic outer shell. When the pressure reaches a certain point (normally within 3-5 seconds) the Thunder B grenade shell bursts open, emitting an extremely high decibel popping sound. After the grenade has burst, simply reset the firing mechanism and load a new CO2 cartridge and shell into the Thunder B core.

The Thunder B CO2 grenade is great for clearing buildings, setting booby traps, and disorienting your opponents. The sound grenades are very safe and do not fire any projectiles, however caution and normal safety procedures should always be practiced when using a Thunder B grenade. Always wear face, eye, and ear protection when using Thunder B grenades. The sound of an exploding Thunder B brings a new level of intensity and realism to any airsoft game. Make room clearing a breeze with the Thunder B CO2 Sound Grenade!

Note: Grenade shells are NOT reusable. CO2 cartridges and grenade shells must be replaced before each use. DO NOT throw a Thunder B grenade towards another player, as the grenades are hard and can be heavy. Always use an under hand toss or roll when using the Hakkotsu Thunder B CO2 Sound Grenades.

5 Hakkotsu Airsoft Thunder B CO2 Sound Grenades Package w/ 3 Shells *****
good and bad things about grenade

"its an extremely affordable grenade and the system is very durable and looks very realistic and it can be filled with bb's, powder, etc. however one problem is the time it takes to explode varies due to the fact that the more stuff you put in it the faster it explodes i definetly recomend this grenade due to its price and i also recomend buying a pack of alot of shells and also a large utility pouch if you have a tactical vest so you can avoid carying it around in your hand."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
