Funny, I was an 031 and carried an FN for 5 years (when I wasn't carrying a C3 or a Browning GPMG) and never broke a handguard and never lost a gas plug.
I may have just been lucky but, for the most part I don't remember a lot of those problems...except...by the s**t disturbers who seemed to make a career
out of screwing up. Mind you, I didn't like cleaning Shi**ers or doing pushups so I generally toed the line. I liked the C1, very much and like most grunts
took pride in taking good care of my rifle. You never knew when the Soviets would come!
I do remember a deuce and a half driving over a section's rifles that they had grounded while eating lunch!
One thing I vividly remember is humping a C2 across Wainwright in the blazing sun, full mag bra and all, with the section commander yelling "C2 Left!", "C2 Right!", "C2 Left!" all afternoon, and giving me a big SE grin every time I ran past him. Almost 40 years later and he is still one of my best buddies.
