Duncan Long is an internationally recognized technical and fiction author with over 70 books that have gone into print. The majority of his books deal with firearms and ammunition, but title subjects include everything from chemical, biological, and nuclear weapons to a health manual and book about becoming a freelance writer. Long has also authored the nine-book action/adventure Night Stalkers series as well as the science fiction novel, Anti-Grav Unlimited and the sci-fi triology, Spider Worlds Tales.

     His firearms and chemical/biological warfare books are in the private libraries of the CIA, US Marines, FEMA, and other US agencies as well as the private library of at least one foreign embassy and the EPC (Emergency Planning, Canada). The FBI has requested that his books be sent to their FTU (Firearms Training Unit) at Quantico. Two of Long's firearms manuals are currently used in one of the International Correspondence Schools' gunsmithing course and an additional manual was written for ICS's detective course.

         Important note: Due to the large volume of e-mail, and several ongoing book projects, Duncan regrets that he is no longer able to respond personally to questions regarding firearms. This page will be updated and material added as his time permits.
