Airsoft Clubs for 11-Year-Olds: Safety & Age Requirements

Question
My son wants to join an airsoft club for compitition he wants to airsoft with people hes 11 and i havent found any that will be ok for him all the clubs that i found were 13 or 18 and over and if you found one would it be ok for him to join like would it hurt alot if he was hit with a gun?

Answer
He would really need to wait till he is 13 or older.
Basically the kid needs to be mature enough to follow the safety rules without flaw. Evan 13 or 14 is bit young for this game.
With the proper safety gear it is safe but it does sting.
Yo need heavy clothes and eye protection.
