If you contact and Age Verifier I'm sure they can get you AV'd within the week. If your planning on playing a game which is why you need a gun. Ask to borrow or rent . It's better like that for your first game anyways cause you get a feel for it all first. Instead of rushing into buying a gun and ending up not liking it or buying a piece of crap.
