The only thing you need to operate this grenade is BBs. No Gas or Co2 is needed.
It has 3 compartments that are under spring tension and it opens by impact, spreading out 130 BBs max.
Thanks to the spring mechanism, it also works in lower temperatures.
Just load the spring, fill in the BBs, and give it your best throw.
The grenades are intended to be tossed from meter-high altitudes to the desired area of effect. Because we cannot ensure their proper use amongst players, we cannot accept warranty claims for broken grenades.
