A lot of it came from the FBI, in money to a confidential informant, to buy the guns. It is one reason for the coverup. There was also a third rifle at the Brian Terry shooting, that was taken from the crime scene. The word is that it was tied to this confidential informant, which is why it "disappeared" from the crime scene.
“There was also a third rifle at the Brian Terry shooting, that was taken from the crime scene.”
