Are you seriously asking this question... because i feel happy today, i'll try not to flame.
No you can't have an airsoft gun at 16 and even if you get one, you would'nt be able to use it on games because you need to be 18 or older normally.
Check the FAQ for your answer and try to not post things like this, it's can be ugly very quick...
edit: I think it's not the first stupid post you make this week. Didn't you ask if you could play in a open field recently?
