A 15 year old legally can own a airsoft rifle and an airsoft pistol. It is advised to always wear eye protection when carrying a loaded airsoft rifle/pistol. I would recommend adult supervision if they are playing but other than that you are fine. Have fun and don't get in trouble!
A 15 year old may use and play with an airsoft gun, however someone 18 years or older must be present and sign a waiver when purchasing as minors cannot legally purchase an airsoft replica on their own.
