So i am Currently bidding on a small Carbon fiber Scuba tank....But im not sure if these tanks meet the US Requirements....this is the tank that i am talking about...i Looked at the same tank on Amazon and It appears to be this very same tank, a Customer who bought one gave a warning NOT to buy this talk because you cant get it filled due to it doesnt have the right Requirements for the good old USA....i am somewhat Relieved that i have been out bidded...i wouldnt pay no more than $135...just lookin for something that can hold me over until i can Afford a bigger tank....i have a big Scuba tank but its only a 3000 psi so i can only fill my gun up to 200 bar...can someone let me know if its a good buy...thanks
