An Army Times article by Mathew Cox describes the problems still afflicting the US military’s primary long arm, and identifies Heckler & Koch’s 416 as the generally desired, but unavailable, alternative.
Ever since the Army’s adoption of the M16 in the mid-1960s, a love-hate relationship has existed between combat troops and the weapon known as the “black rifle.”
It’s accurate and easy to shoot. Plus, the M16’s light weight and small caliber helped soldiers carry more ammunition than ever before into battle.
The M16, however, has always required constant cleaning to prevent it from jamming. The gas system, while simple in design, blows carbon into the receiver, which can lead to fouling.
The Army has decided to replace most of its M16s with the newer M4 carbine. The Army started buying M4s in the mid-1990s but mainly reserved them for rapid-deployment combat units. Its collapsible stock and shortened barrel make it ideal for soldiers operating in vehicles and tight quarters associated with urban combat.
Experts, however, contend that the M4 in many ways is even less reliable than the M16.
Special Operations Command documented these problems in a 2001 report, “M4A1 5.56mm Carbine and Related Systems Deficiencies and Solutions: Operational and Technical Study with Analysis of Alternatives.”
The M4 suffers from an “obsolete operating system,” according to the report, which recommended “redesign/replacement of current gas system.” It describes the weapon’s shortened barrel and gas tube as a “fundamentally flawed” design and blames it for problems such as “failure to extract” and “failure to eject” during firing. “The current system was never designed for the rigors of SOF use and training regimens — the M4 Carbine is not the gun for all seasons,” the report concluded.
