Check out this picture posted on TheFirearmBlog of a bunch of machine guns at a museum in California that were made inoperable. Sad. Almost as sad as this gun graveyard in Asia full of rusted WWII and Vietnam War era guns.
This photo was taken by me at the former Military Vehicle Technology Foundation (aka the Littlefield Collection) museum in Portola Valley, CA. All of the formerly full-automatic weapons you see before you were rendered inoperable in preparation for leaving the state. This included torching both the receiver and barrel. Most of what you see in the photo are M1919s and MG42s. A number of other weapons were chopped up as well.
