A Thunder B is an Airsoft simulation grenade that emits noise. It holds a standard 12 gram CO2 cartridge in a fully sealed compartment. Upon pulling the pin, the fire lever, or spoon, snaps down puncturing the CO2 cartridge and starts releasing the pressure from the cartridge until the shell breaks due to air pressure inside the shell resulting in a loud pop sound. The Thunder B Spare Core is perfect as a replacement set and also allows you to have several active Thunder B Grenades any time. Simply keep them safe in a pouch or bag for when you need them.
Package Includes: Aluminum CO2 cartridge housing, Core Cap w/ Fire Lever, Rubber Core Bushing, Metal Washer/Spacer, 2x Safety Pins
Spare shells available in pineapple and sound flash tube. Each shell is one time use. Spare shells are available at great prices. (Please recycle the shells after usage)
Spare fire lever and pin also available at great prices. Each fire lever lasts about 20+ use.
When not loaded with a CO2 cartridge, the thunder B is a very nice decorative and a bb holder.
