Back to rifles. Perhaps surprisingly, given the AR-15 line's history, I find the M4s and M-16s are generally well-liked, as far as 5.56-millimeter rifles go. I do read a lot of complaints about them on-line, and while some fraction of those complaints are probably true, many have the feel of urban legend. A large fraction of what you hear is unverifiable, and the failures described are not accompanied by essential information--the names of people involved, the dates and locations of the firefights, the units involved, descriptions of steps taken after to report and remedy the problems. Over the years, when I have been in the field and interviewing soldiers and Marines involved in the fighting, I have not been able to replicate these complaints, and I have grown suspicious of them. And in the many firefights and engagements I have been present for, I have yet to see an M-16 jam or have some other stoppage. I'm open to being wrong here, and I invite anyone who has fresh information to share it with me. Until I see better evidence, I'll go with what I hear and have seen first-hand, which is that Colt's and FN's current M-16 variants are generally regarded as rifles that work--again, within all the limits of the current NATO-standard 5.56-millimeter round.
