I have used and carried a number of different M60 machine guns. I fired three M60's during Basic and AIT at Fort Benning, all were 100% reliable for me. I carried two and fired four (at different times of course) M60's while assigned to 1st BN / 7th INF in Germany. They were all 100% reliable, even with blanks and a properly adjusted blank adapter. I also fired M60's while assigned to National Guard units in Arizona, Oregon and Ohio that were 100% reliable. Operator error is the number one cause of most problems with most weapon systems.
Guns cause crime like spoons cause Rosie O'Donnell to be fat!
I hunt, therefore I am.
