From the Scripps Howard News Service:
"A new statistical snapshot of firearms commerce in the United States shows the nation imports about 16 times more guns each year than it exports.
A recently released report by the US Bureau of Alcohol, Tobacco, Firearms and Explosives calculates that in 2010, the United States imported more than 2.8 million firearms.
U.S. exports in 2009, the most recent year with comparable data, amounted to only 195,000 firearms. As in years past, Brazil by far led the world in firearm exports to the U.S. last year with about 741,000; all but 215,000 of those were handguns. Canada shipped the most rifles of any country - 155,000 - to its neighbor to the south.
The ATF report also maps the location of the 2.85 million registered weapons in the nation last year. California came in first, with 243,000, followed by Texas (224,000), and Virginia (202,000). Virginia is the machine-gun capital, with 28,700 registered. Pennsylvania is home to the most short-barreled shotguns, 11,000. The most silencers (29,000) can be found in Georgia. The most short-barreled rifles (11,000) were in Texas."
Considering the number of SKS's and AK clones imported into the US. I would have thought that the old "iron curtain countries, including China were the biggest exporters of firearms to the US.
