It's only 18+ to purchase airsoft guns.
But I am not sure about permission sheets, and all paper work for it.
Check with your town, there might be bylaws and zoning issues.
Issurance will be an issue as well, since you don't fall into paintball field issurance. A simple waiver will most likely get raped in court if something really bad happens.
Point is, you need to reasearch a lot. Contact other local fields to see how they are set up.
