From NRA-ILA:

As we reported in June, the Obama Administration’s State Department (DOS) proposed a revision of the International Traffic in Arms Regulations (ITAR) on June 3 that would require anyone seeking to make certain types of information about firearms publicly available to first obtain government approval. Prior restraints of the sort contemplated by the proposal are among the most disfavored regulations of speech under First Amendment case law. Our original alert encouraged gunsmiths, manufacturers, reloaders, serious hobbyists, and others who rely on design, development, production or manufacturing information about firearms to file comments with the State Department opposing the rule and explaining its problems.
