The Thunder B can be attached to any tactical vest. It's colour, shape, operations and handling are very similar to the real grenade used by military forces around the world which make it incredibly fun to use!
The Thunder B generates a noise level of 130db which is as load as a jackhammer or a plane flying overhead so do be careful as the noise may be a little louder than you anticipate.
Here are the directions on how to use it:
Pull the hammer all the way down
Insert the safety pin
Insert the trigger pin to lock to trigger hammer
Screw the end cap to cylinder
Insert 12g disposable gas into cylinder cover
Push the rubber fixer into the cylinder cover
Screw the cylinder cover to the installed striker head
Screw the whole part into the Thunder Shocker Shell
The Line on the shell indicates the explosive direction
