What I'm Bringing

If I am able to come to upcoming games I was bringing a JG G36c and a small spring pistol, I have some acus to wear and a Tactical Vest. I need to know if I need anything like parental consent or what not. (Im 17 ill be 18 this july.) and anything else you might recommend I bring. Ill probably bring water too. Also, are there any game variants or rules on whether or not hits on guns count? Maybe if the gun is hit it is out of commision. So Should I possibly bring a sidearm? All the info on what I need to bring would be great. Thanks =] Hope to be out there soon!
