The official Grease, Rifle NSN 9150-00-754-0063 right now is Lubriplate RG-62-A (aka Lubriplate 130-A) made by Fiske Brothers Refining Co. That is the only product listed on the Military Qualified Products List. Reference: QPL-46003-10.
Personally, MD Labs XF7 works for me. I'm working on a FAQ, The M14 and Soft Lubrication. When done, I'll have it posted at www.imageseek.com/m1a
