This is a nice interactive infographic made by Google for those interested in the exports and imports of arms around the world... "The mapping arms data (MAD) visualization of small arms, light weapons and ammunition transfers was produced by Google as part of the Google Ideas INFO (Illicit Networks, Forces in Opposition) Summit with support from the Igarape Institute and data provided by the Peace Research Institute Oslo (PRIO) small arms database.

The PRIO database contains more than 1 mllion records of exports and imports of small arms, light weapons and ammunition across 250 states and territories between 1992 and 2010. The full MAD tool is available here."

Too bad it does not give info about airsoft guns, or else it would be a great resource for airsoft vendors and players. You can click on the image below to go to the infographic. It's interactive so you can rotate the globe and click on a country name to bring up the information. You will need Google Chrome to view this.
