The Thunder B Player Package D is a great way to get started with thunder B Grenades! It includes a core which houses your 12 gram CO2 catridge. It also includes 12 of the disposable shells. When you pull the pin and release the spoon, the CO2 cartridge will puncture allowing pressure to build up in the external shell, the shell then bursts with a loud bang. These grenades are a great way to enhance the player experience in a Milsim game.
