a new kind of airsoft granade from my supplier, they looks the the "pineapple" granade used in WW2 by US army. It is gas powered, and wont shoot out BB, but use baby powder, and re-useable. so I think it works more like "smoke granade", there will be 2 version, metal and plastic, Price will be around $20 each.
我咩都唔知....
