In another thread, "Best 30 Caliber Battle Rifle" the AR platform came up and then the unreliability of the M16 in early form issued in Vietnam when it replaced the M14. I have heard much urban legend surrounding this issue but have always been puzzled because of my twenty years of experience in the U.S. Army with the weapon. What I found was new information which was very interesting. So as the thread meandered away from the subject and I don't know how to or if you can redirect a thread so I thought a new thread would be the answer as there is obviously more good information out there. Here I will include the salient points. The first reference was from Therewolf: To which I replied: Then Johnny357 gave us a good reference: And Johnny357 also said: Also therewolf ammended: Also from Johnny357: To which I replied: OK, if there is any other good information out there please submit.
