Explain to them if they bought you them then they should let you use them how they're so possed to be used, in a Airsoft WAR :) also tell them all you need is ear protection and eye protection and your set. See Ya out there Soldier ;)
Wear glasses, keep them unloaded with the mag out, don't shoot animals or people unless your in a war and talk to your parents about gun safety. I don't know if your gun people but airsoft guns are safe if you don't do any stupid stuff with them. Also did they buy you AEG, gas or spring?
