Finally got mine yesterday after ordering it from the UK November 17th. I live in the United States Michigan to be exact and it was held in a secure facility by customs. The package contained no primers no blanks basically totally legal especially when you take into consideration there's a lot of things like firearms you name it with practically little to no restrictions versus other places overseas. I got the bang 22 grenade that uses a 22 power cartridge that's used to shoot bolts into concrete no problem, Taginn flash bangs that are 10 times louder than this and the bang 22 put together even had to have explosive stickers on the packaging $30 hazmat fee with no problem. I respect customs for doing what they do as they have to seek out thousands of packages a month but come on this one uses a 209 shotgun primer. All in all I cannot believe how heavy it is the construction is quite premium. LOL the second time I called international customs being completely polite I asked them why is this being held there's no pyrotechnics in it I have two safes full of firearms I can walk in a gun shop where I live and walk out with a firearm IDK maybe that held it up a little longer 😂. But I really have to give hats off to the hakatsu thunder B, more expensive absolutely when it comes to buying the CO2 cartridges and one time use plastic shells which the dumbbell ones are without a doubt the best but no fire no pyrotechnic and extremely loud.
