This is a Airsoft innovations Tornado 2 gas grenade. This thing is amazing and scary when it goes off. This thing is pretty reliable and I’ve never had any issues with it. I’ve fielded it three or four times. I don’t use it enough to keep it so I’d rather someone else have fun with it. It comes with a patch extra pin and grenade lube. I also tied a red ribbon and tied the pin to it so it’s harder to lose it. I’m asking $100 shipped
