Yea... now that you mention it, full-auto is probably what their talking about when they say 'too-light'.
The information I got is from a thick book on Veitnam. It'll give you anything and everything you ever wanted to know about that war, from the beggining, to the end. It's actually pretty good 'thrown' reading. I just love these stories these guys have about that place. I got a laught the other day when they were talking about c-rations. This guy said, "If you didn't like Lima beans, your life was hell, becuase that's all they had. Ham and lima beans. They called them 'Ham and Motherfuckers'... ".
It's also cool becuase a budy of mine was in NAM and I'll talk to him about these stories and he'll add on to them, giving me a better picture.
oh,,.... were talking about ar10's.... sorry.
Thanks for the info.
