"The AK-47 is a recent addition to a collection that’s among the toughest tickets in the country for museumgoers. Tucked into various hallways at CIA headquarters in Langley, Va., the museum displays the gadgets, artifacts and trophies of 70 years of spycraft, from World War II through the War on Terror. The museum is closed to the public and is only visited by employees and invited guests. It is rare for cameras to be allowed in.
The Russian-made assault rifle, identified on a simple brass plaque as “Osama bin Laden’s AK-47,” shares a glass case with an al Qaeda training manual found in Afghanistan soon after 9/11.
"This is the rifle that was recovered from the third floor of the Abbottabad compound by the assault team," said curator Toni Hiley. "Because of its proximity to (bin Laden) there on the third floor in the compound, our analyst determined it to be his. It's a Russian AK with counterfeit Chinese markings."
Neither Hiley nor the agency will say how the AK-47 got to the museum, other than that the agency director at the time of the operation, Leon Panetta, "asked that it come into the museum collection," said Hiley. But one source told NBC News that it came from the "dark side" of the agency, the operations staff that worked with the SEALs on the May 2011 raid."
"The agency also will not comment on the specifics of how the weapon was recovered or whether it was loaded when retrieved.
"I wasn't there," said Hiley. "So I can't confirm or deny exactly where the weapon was. I just know that I have it in my museum and I'm happy to have it."
