At the end of 2012, the reported price of an AK-47 on the black market in Afghanistan was $1,500. Three years prior, the reported price was between $600 to $700 in the country. The price for grenade launchers, pistols and PK machine guns have also risen in 2012.
The rise in prices for weapons is caused by increased demand for firearms in anticipation of international forces leaving Afghanistan.
