just tried to buy some on eBay and got this:
"It appears this item is restricted for export by the U.S. Department of State (DOS) under the International Traffic in Arms Regulations (22 CFR, Parts 120-130) or the Department of Commerce under the Bureau of Industry (BIS) and Security Export Administration Regulations, EAR (15 CFR, Parts 730-774). ITAR restricted items require an export license granted from the DOS Directorate of Defense Trade Controls (DDTC) prior to export. EAR restricted items may or may not require a license, depending on the end user and the ultimate country of destination.
Directing the seller to export without complying with the regulatory licensing and documentation requirements is a violation of United States law. Please consult DDTC’S website at ww.pmddtc.state.gov and BIS’S website at BIS Redesign for more guidance. Also, please refer to eBay’s Military Items Policy for additional information."
