The question has been posited as to whether or not Frog Lube is suitable for use on an M1A rifle. Several responders on various web sites questioned the film strength for EP use on such an application as the rails and bolt on the M1A.
I would respond that I have used FL in place of Imperial sizing wax for full length sizing of .308 cases and it does very well in that application. This suggests to me that FL is suitable for high pressure applications. I once even tried 80-90 gear lube for this (sizing) and immediately came close to sticking a case.
