A modern icon, the M16 has been used by US armed forces since 1964. What's there to be said that hasn't been already? It's #2 on the list due to its active use in Iraq and Afghanistan, and it has spawned countless copies, myths, and legends in the past 40+ years. An early reputation for misfires and jams reminds one of the ill thought-out Top 21 gun count here on this blog, which while interesting enough to remind us of the bizarro-world place that guns hold in our society became painfully long running. A similar criticism to the M4 holds: with a military budget approaching $1 trillion, shouldn't the US soldier carry the very best rifle, not one that's merely good and that is superceded in many areas by other guns?
