This full on gas powered grenade is designed to meet the demands of any situation. It can be set for timed detonation, ensuring that you get the coverage you need when the time is right. Uses a piston mechanism and spring to open the grenade and release the BBs after the pin is pulled. The grenade hinges at the bottom so you arent hunting for two halves after you use it. Designed to 1:1 scale, these 6mm grenades are non-explosive and completely reusable.
