The Thunder B training grenade is one of the most dynamic training flashbangs available. Easy and cheap to reuse, the Thunder B is an ideal training tool for airsoft, law enforcement, or other tactical training. While other training flashbangs or distraction devices use proprietary charges and require complicated setup, the Thunder B uses commonly available 12g CO2 cartridges and the inexpensive replaceable shell casing to provide over 120db on detonation.
This spare shell kit has 12 spare Flash Blank style outer shells for re-use with the Thunder B training grenade core set. These Blank style shells are similar to the actual flashbang devices.
