Chris, I bet the oil is adequate. One thing for sure, the metal is slippery.
After trying the oil sample, I went ahead and purchased some oil from them.
It may be somewhat controversial, but I do believe that US military forces use it on their firearms.
After thinking about it, I still feel more comfortable seeing some grease on the R9, either Militec or SuperLube, in addition to the Militec-1 oil which was applied with my wife's hair dryer.
