Gunkid, please post the sources of your statements, when you choose to make a fool of yourself. Keep in mind, gunkid has stated publicly that he has minimal knowledge in cleaning the AR/M16 system and shooting also. I have no problem at all making 3 rd 3" groups at 100 yds with my stock Garand.
Being that your friend was Air force, I would assume that he has had minimal experience with firearms, period. The Garand, the M14 and the AR/M16 series are all very easy to clean providing you have had competent training and practice.
