SurvivalBlog reader L.M. alerted me to an informative article at Armalite’s web site about how automatic transmission fluid can be used as a firearm bore cleaner, and how motor oil can be used as a gun lubricant. Even if you are committed to Break-Free and Hoppes #9 (like me), this is good to know WTSHTF [4] and cleaning supplies get scarce. See: http://www.armalite.com/library/techNotes/tnote64.htm [5].
