I'm not sure why this is unlocked now, but I just have to say something about weight. Gone forever are the days when you could cram all kinds of crap into your luggage. First the airlines tacked on a rigid 50 lbs per bag limit and now they just charge extra. Bummer. And BTW, you're limited to 50 lbs per checked bag for taking a bus, too, now. So, when making your weapons, think seriously about weight. A solid resin blaster is heavier than you think. Go for hollow weapons whenever you can.
