In Cambodia and Thailand, I think it's assumed that there aren't any markets in the United States of America. However, there are markets called Flea Markets, which are markets where anybody can sell their second hand stuff. At a lot of these flea markets, people are selling their private guns, especially rifles, as well as knives, bows, ammunition, and all sorts of other things.

Here is a partial tour of Smiley's Flea Market in Fletcher, North Carolina, USA. They're open most days, but are most popular on Saturdays and Sundays.
