Thanks for the kinds words Glenn.
I use that particular product at every class- and have for the last 4 years or so.
The majority of those who talk guns haven't the slightest clue as to what keeps an M4 running. We used to see a laege number of students attending class in the same boat, but it is changing around now.
People finally are getting the word that the M4 platform needs lube- more is better, and what you use isn't as important as where you use it.
Glad you enjoyed it!
