I received a reply almost right away saying:
"Yes we use United States postal service for our shipping carrier which will ship to PO boxes "
So, boom. Problem solved. Now I'm wondering about that strap, though. Can it ONLY wrap around your neck? I was under the impression that it could be adjusted and slung around under your armpit and across the side of your neck, traditional diagonal style.
Can anyone who owns this sling (or knows someone who does) confirm exactly how modular it is?
As a second option, I was also considering picking up one of these: http://www.airsoftatlanta.com/v/vspf...os/64516-2.jpg
...and attaching a CQB sling to it so that I may transition shoulders easily (unless transitioning shoulders works just fine with The Vest Guy sling?).
