The purpose of this stun grenade is to attract the enemies' attention or disable them for a short period of time to breach their defense without "killing" anyone in the room. It perfectly suits "hostage rescue" training scenarios. It may also be used as a frag grenade simulator where fragmentation projectiles are not allowed. This "Flash-bang" imitation effect grenade is the scaled version of the FBG-6. Compared to the FBG-6, it has a lower sound report and smaller dimensions, which will allow you to use it indoors, and store them in standard 40mm ammo pouches. All parts include a safety lever made of highly safe polyurethane material and can't harm anyone properly equipped for the training.
