I was curious if the TLSFX Thermobaric Multi-Bang Grenades were legal to use in the United States as I know that they are legal in the United Kingdom.
They would be very useful when engaged in CQB as they are flash bangs/stun grenades but intended for airsoft. I do not know of any airsoft companies/stores within my state that is selling them, but there are a few UK airsoft websites that are selling them for 3.80 pounds
The short answer is: No, they arent legal. No one in the US sells those (at least that I know of), and I dont believe its legal to ship them from the UK to the US, for the same reason you cant order fireworks online and have them shipped to your house. I've looked into getting some myself, but I came to this very dead end.
