The Valken Thunder V2 Co2 Sound Simulation Grenade Core is the next generation of Valken Thunder V sound grenades. This airsoft simulation grenade core is powered by a single 12g Co2 cartridge and emits noise only when used in conjunction with a single-use shell (sold separately). We recommend that the firing lever and pull pin are reset fully before inserting a Co2 cartridge to prevent pre-mature detonation during assembly. The core holds a standard 12-gram Co2 cartridge in an enclosed compartment. Once the pin is pulled, the firing lever will release once and puncture the Co2 cartridge pressurizing the disposable shell (sold separately). Approximately 3-4 seconds later the shell breaks due to the air pressure resulting in a loud bang! We recommend using our Valken Thunder V2 Spare Replacement Shells with this airsoft grenade core.
