How it works

The Thunder B core holds a standard 12 g CO2 cartridge: once activated, the gas fills the shell until the pressure bursts it with a bang of over 130 dB. The grenade uses no gunpowder, so there is no flame, and after use you simply replace the cartridge and the shell to throw it again.

In the field

The cylindrical shape recalls the grenades issued to the armed forces and sits comfortably on a vest or in grenade pouches. It is the ideal supply for CQB and MilSim games, and it also works with Specna Arms Vapor kits. The shells are single use: after the bang, pick them up and put them in plastic recycling.

Warning: use only during airsoft activities, with suitable protective equipment and in accordance with field rules.
