Thunder B Co2 Airsoft Paintball Simulation Sound Grenade (12 Shell Set / Distraction Grenade)
by Brian C. Date Added: September 6, 2011
f you are going to buy the Hakkotsu Sound grenades, these are the only ones you should fool with. They are extremely loud and they activate without any modification. The other versions, including the Version 2 or 2011 update come with the original core, which means no consistency and sometimes no bang.

This version comes with the new core which includes the following modifications.
1. A stronger spring on the hammer to ensure the CO2 canister is punctured.
2. A longer punch to ensure deeper penetration.
3. A hole in the lower cap that "meters" (speeds flow of gas into the distraction device) the gas glow
4. A better design on the sound canisters. They form a better seal and the shape forces a rupture at the same place every time for more consistency.

Looks realistic
Consistent activation times (3 sec)
Extremely loud - even in an open area outside
Easy to load - No need to screw on additional pieces that are easily lost and fail to work anyway.

None in comparison to the 1st generation cores.

Make sure your core has a hole in the bottom as this let's you know it is a second generation core.
