The M16A4 is not completely gone; it will remain in the armories of some training and non-combat units in the Army and Marine Corps. It’s also possible that surplus rifles may be modified for other roles, such as designated marksmen rifles. But the ubiquitous name of the M16 in modern culture will likely be replaced by ‘M4’ when referring to America’s premier infantry weapon.
The Army is botching the procurement of what should be one of the simplest weapons to buy: the pistol. Senate Armed Services Committee Chairman John McCain will soon issue a report called “America’s Most Wasted: Army’s Costly Misfire.” It says the Army has spent 10 years preparing a competition for a gun that will cost about $500. During all that time, he says, the Army has little to show but a thick, complex requirements package that perplexes gun makers and may produce a rigged result.
