Yeah, for sure you're making it up. I doubt you were alive in 1973.
I was in the Marine Corps in '73, you fool! We trained at PI with M-14s, not M-16s. I actually like the M-14 better, even though it weighed 11 and a half pounds to 7 and a half and the rounds were much heavier, about 2 and a half to 1. Humping around, the M-16 was better, because of the weight difference of the weapon and ammo. What else do you want to know, maggot?
Here is what it boils down to. You're a right-wing idiot. I'm old enough to quiz you and find out how old you are, though it would be hard for me, because you're a stupid person who probably knows little about the world they lived in. You right-wingers are ridiculous, because you think you know things and you don't know shit.
