MSNBC is apparently now highlighting the fact that AR 15 type carbines are prone to failure especially during lengthy firefights when many rounds have been fired. Normally I'd dismiss something like this in the news as sensationalism, but it seems to me that pretty much "everyone knows" that M4/M16 rifles begin to malfunction if you feed over 500 rounds consecutively through them. The article pretty much is articulating something that people knew for a long time, but at the same time it has got some specific examples of failures at crucial times.
Far be it from me to call myself a firearms expert, but I never fully understood why most people I talk to seem to consider something reliable but less accurate, like a Mini 14, to be inferior to something with more accuracy but which is a lot more likely to fail, like some kind of AR. I figure that if you're under a lot of stress you lose a lot of fine motor control anyway so the single most important thing with a firearm has got to be reliability.
Anyway, here's a link to the article with some quotes: http://www.msnbc.msn.com/id/33267598/

The study by Douglas Cubbison of the Army Combat Studies Institute at Fort Leavenworth, Kan., hasn't been publicly released. Copies of the study have been leaked to news organizations and are circulating on the Internet.
Cubbison's study is based on an earlier Army investigation and interviews with soldiers who survived the attack at Wanat. He describes a well-coordinated attack by a highly skilled enemy that unleashed a withering barrage with AK-47 automatic rifles and rocket-propelled grenades.
The soldiers said their weapons were meticulously cared for and routinely inspected by commanders. But still the weapons had breakdowns, especially when the rifles were on full automatic, which allows hundreds of bullets to be fired a minute.
The platoon-sized unit of U.S. soldiers and about two dozen Afghan troops was shooting back with such intensity the barrels on their weapons turned white hot. The high rate of fire appears to have put a number of weapons out of commission, even though the guns are tested and built to operate in extreme conditions.
...
Cpl. Jonathan Ayers and Spc. Chris McKaig were firing their M4s from a position the soldiers called the "Crow's Nest." The pair would pop up together from cover, fire half a dozen rounds and then drop back down.
On one of these trips up, Ayers was killed instantly by an enemy round. McKaig soon had problems with his M4, which carries a 30-round magazine.
"My weapon was overheating," McKaig said, according to Cubbison's report. "I had shot about 12 magazines by this point already and it had only been about a half hour or so into the fight. I couldn't charge my weapon and put another round in because it was too hot, so I got mad and threw my weapon down."
The soldiers also had trouble with their M249 machine guns, a larger weapon than the M4 that can shoot up to 750 rounds per minute.
Cpl. Jason Bogar fired approximately 600 rounds from his M-249 before the weapon overheated and jammed the weapon.
Bogar was killed during the firefight, but no one saw how he died, according to the report.
