I'm not sure 14 year olds can even purchase clearsoft (buyairsoft is 18+ only)
But, I'm sure you'll get what you pay for. You'll get a clear gun with a plastic mechbox that will probably break and you'll be left with no parts. It's not even airsoft.
You're probably better off playing paintball or something until you are 18 (this isn't your first thread either)
Not trying to be mean but those are the ropes man
