Amongst the items recovered from the hideout of drug lord Joaquin "El Chapo" Guzman after his capture in a January 8th raid was large cache of firearms. Today, sources are claiming that one of those weapons, a .50 Caliber sniper rifles, was obtained by the kingpin through the so-called "Fast & Furious" program.

According to Fox News:

When agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives checked serial numbers of the eight weapons found in his possession, they found one of the two .50-caliber weapons traced back to the ATF program, sources said.

Federal officials told Fox News they are not sure how many of the weapons seized from Guzman’s house actually originated in the U.S. and where they were purchased, but are investigating.

The .50 caliber rifle, similar to the one pictured above, fires the robust .50 BMG round and has an effective range of over a mile. In addition to its capacity as an anti-personnel sniper rifle, the weapon is also an anti-material rifle. In the right hands, it can be used to disable cars and even helicopters, making it a favorite of armed forces and criminal elements around the globe.

The discovery comes at the worst possible time for the Obama administration as just yesterday a federal judge rejected the president's executive privilege claim over records pertaining to the controversial Fast and Furious "gun walking" program.
