Quite honestly, unless you're shipping your paintball gear from one place to another in the US or within the EU, I would NOT recommend sending your stuff through the postal service for any reason, nor given recent events even attempt to fly with it. The latter portion pretty much speaks for itself, and the mail experience, well, anyone in here that knows me knows exactly why -I- don't send paintball stuff through the mail, and if you haven't heard why either ask them or ask me and I will repost it gladly, because it's something that the paintballing community needs to all be aware of. Let's just say if I say don't do it, there's a reason that I don't do it that the reason should be reason enough for you not to do it.
