[ARCHIVED THREAD] - Evolution of the bolt and carrier group of the M16

Posted: 7/14/2002 8:20:38 AM EDT

Since its introduction in Vietnam, how has the original M16 bolt and carrier group changed? I was having the old and tired discussion about the reliability of the M16 in Vietnam and wondered what changes have been made. I know that there were other factors like ammo problems that gave our boys a hard time over there, but what else about the design has given the M16 its undeserved reputation?

Thanks,
Brian

That's classified information, Dr. Rumorie.

THe only changes to the bolt/carrier I'm aware of are the addition of the FA notches and later the change to the ejector spring/buffer for the M4. All the problems in Nam were related to incorrect powder and poor (non existant) maintanence. The biggest change to the actual rifle was the chrome bore and chamber.

There have been numerous changes to the bolt carrier group. different firing pins, fp retaining pins, weights of the carrier itself, chrome plating, gas tube keys. Pick up a copy of The Black Rifle from Collector Grade Publications, it goes into great detail.

Weren't most of the changes you are referring to made during the design stages of the original rifles? I was talking about *since* Vietnam.

Thanks guys, that was the kind of info I was looking for. I mentioned the chrome lining, lack of training and maintenence, powder selection and all of the other things to this guy and he just doesn't seem to get it. I guess you can lead a horse to water but you can't make 'em drink!
