Oh HELL NO! I ain't trusting the luggage monkeys with any of my stuff. Especially with NFA items. Besides.....you have any idea what it would cost to ship a gangbox full of rifles and ammo to AZ from the hood of MD (Reagan or BWI)? Plus...the sheer dollar value of what's crammed into that aforementioned gangbox. I ain't bragging or nothing, but that's a $hitload of dough that I cram into that box. Hell....6+ of it is probably just glass/optics alone, and another 4 in cans. Then you add in the actual weapons? I ain't checking that at any airport. Unless the bird has a giant 308AR emblem on the side of that krylon black, beat up C-17 that Doc traded for that microphone way back when (and pissed Jon off).
There's a reason I don't like to let it outta my sight until we're out in the middle of the desert (getting drunk of course).
