I bought a Nikon ProStaff 3-9x50 on American eBay in the summer for $160, and it's been sitting in a friend's house in New York since then. Now someone I know is going over there for work, and has offered to bring it back in their check-in luggage. Anyone know what's likely to happen if he gets stopped at customs? I assumed he might just have to pay a bit of duty, but I was in a gun shop the other day and they said anything over 4x would be classified as military-grade, and he might therefore get into trouble. I'd always thought anything under 10x was ok. Any advice or similar experiences gladly received!
