I'll say this, I've personally fired so many rounds through an AK that it was so hot I could no longer hold it. It was a Bulgarian full auto AK in Iraq. The RPK also, never stopped. The slop in the system keeps it going. Our weapons are created with tighter tolerances. IMHO

Weapons failed U.S. troops during Afghan firefight

WASHINGTON - In the chaos of an early morning assault on a remote U.S. outpost in eastern Afghanistan, Staff Sgt. Erich Phillips' M4 carbine quit firing as militant forces surrounded the base. The machine gun he grabbed after tossing the rifle aside didn't work either.

When the battle in the small village of Wanat ended, nine U.S. soldiers lay dead, and 27 more were wounded. A detailed study of the attack by a military historian found that weapons failed repeatedly at a "critical moment" during the firefight on July 13, 2008, putting the outnumbered American troops at risk of being overrun by nearly 200 insurgents.

Which raises the question: Eight years into the war against the Taliban in Afghanistan, do U.S. armed forces have the best guns money can buy?

The military insists that they do, but a small but vocal number of troops in Afghanistan and Iraq has complained that the standard-issue M4 rifles need too much maintenance and jam at the worst possible times.

Complaints about the weapons the troops carry, especially the M4, aren't new. Army officials say that when properly cleaned and maintained, the M4 is a quality weapon that can pump out more than 3,000 rounds before any failures occur.

The M4 is a shorter, lighter version of the M16, which debuted during the Vietnam war. Roughly 500,000 M4s are in service, making it the rifle troops on the front lines trust with their lives.

Sen. Tom Coburn, R-Okla., a leading critic of the M4, said Thursday the Army needs to move quickly to acquire a combat rifle suited for the extreme conditions U.S. troops are fighting in.

U.S. special operations forces, with their own acquisition budget and the latitude to buy gear the other military branches can't afford, are replacing their M4s with a new rifle.

"The M4 has served us well, but it's not as good as it needs to be," Coburn said.

Battlefield surveys show that nearly 90 percent of soldiers are satisfied with their M4s, according to Brig. Gen. Peter Fuller, head of the Army office that buys soldier gear. Still, the rifle is continually being improved to make it even more reliable and lethal.

Fuller said he's received no official reports of flawed weapons performance at Wanat. "Until it showed up in the news, I was surprised to hear about all this," he said.

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. The weapons, though, 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.

It does appear that the mechanics of weapon evolution has advanced by leaps and bounds whereas the materials of weapon construction has lagged behind.

Carry 2 M16 types or 1 AK?,,,,,,I would pick up an AK so fast your head would spin. The M16 is a great weapon for certain work but there are better/more reliable weapons out there. M14,CETME types, AKs in 223 cal. Put those in the US troops hands and M16 with optics as the M1 Carbine was used in WW2,,,as rear or support troops or officers who dont need a full size weapon. My son is in the Corps and if he has to go over there he knows all too well to pick up an AK.
My neighbor has an AK in .223, so we(US) could make them and issues them if we 'have" to keep that caliber.

M16's and all the varients are excellent weapons when thay can be kept clean. The problem is how do you keep them clean in the middle of a firefight? Every soldier that has ever carried a M16 knows that cleaning he weapon regulary is manditory. But a sustained firefight cab foul one way to easy for me. I had on a combined fire range had to expend over 2,000 rounds of 223 amo. I went thru 6 m16's to do it. Every one of them jammed because thay fouled internially. I dont like the M16 and never have. In the Gulf war I would regulary pick up an Ak that had been laying in the dirt for who knows how long. With 1 exception thay all fired perfectially and all I did was shake them a little. AS a combat engineer I was tasked to destroy weapons stockpiles. We did everything imanagible to kill AK's. Including running over them with an 11 ton M113. The only thing that actually worked was to pile them in an enclosed space and judicous use of C4. In Nam when it was first introduced it was hard to keep operational because it needed so much cleaning. The forward assist is a modification to the original design because the bolt cant be trusted to seat itself completely. Our soldiers need reliable weapons with decent firepower. If I was ever given any of the M16 variations as a gift I would sell it and buy something decent.

Just my 2 cents and honestly worth not a penny more :)

It strikes me odd that this 'issue' is only showing up 8 years into the war.

Also, the guy says he shot 360 rds in 30 min and his weapon was too hot to chamber a round... sounds like there's more to the story to me.

they exceeded the amount of sustained fire.Other words they were shooting too many bullets too fast.You can shoot an M4 indefinitely firing 15 or 20 rounds per minute .If you exceed that amount your barrel is going to get too hot it'll start cooking off rounds then It will fail to fire altogether if you don't let it cool down.The AK's will get so hot they'll start cooking off rounds too.They are not immune from getting too hot.An AK will get too hot also if you keep a high rate of fire going.
I've seen them both cook off rounds .I've seen M16 barrels so hot if you leaned it on a tree the tree would start smoking.

Always seems that they find someone who can complain about the gear. If they had AKs the article would be about how inaccurate it was or how noisy it was (and thus unsuitable for "quiet" actions).

360 rounds in 30 minutes? something about the old saying about not being able to miss fast enough comes to mind. That kind of rate of fire is the domain of the SAW, (yes I saw they complain about one of those as well)

I have personally shot an ar-15 (an unmodified colt) that had not been cleaned for 2,000 rounds, I put another 1,400 of rapid fire through it without even removing the bolt and I've been told it went another 8,000 under similar (carbine class) conditions before even the bolt was cleaned, so dont tell me that the ar15/m16 platform has to be "white glove" clean to function.

My guess is with that amount of fire and heat that a good number of those guns suffered from ammo related failures (pop a primer down into the fire control group and see how many more rounds you get off).

How do these complaints stack up against a piston driven upper such as the Ruger sr556 and Sig-556?

they seem to keep the action much cleaner/cooler than a gas driven system. The barrel heat isn't something you can really overcome us it?

very much cleaner as far as the in the action, in fact I think all of the IAR (marines request for a fully auto M16 basically to replace some (not all) of the SAWs) contenders are pistons (and some have some pretty hearty heat dissipation devices built into them, as well as that many of them fire in the full auto mode with the bolt OPEN between shots to help cool the gun between shots (first shot from the bolt closed to keep the dirt out)).

Generally however the piston-AR is considered to be a solution in search of a problem and there is concern of how adding more parts to the design will help reliability (personally I do have an LWRC piston).

I checked another board that is mostly military vets and their support people for their take on this article. There, the barrel heat kept coming up (mostly in the context of "yeah you cant shoot that much even with an AK, the handguards would be too hot to hold/likely start smoking"). Basically the take was that a ROF that high was undisciplined. I also found a link to the full preliminary report (apparently there will be some major revisions and that author isnt particularly happy with the media report based on it).

Another 2 cents for the group (not sure mine are worth that much) but in multiple environments during sustained engagements as well as sporadic fire I have used the M16/M4/AK as well as M9. The M16 and M4 if cleaned almost daily are plenty reliable if fired at a sensible rate of fire, they are not support weapons therefore of course aren't going to operate very well in a "spray and pray" role. The AK is a fine rifle with ammunition abound in most areas, 'nuff said. The M9 is ok if it is a brand new one and your using it within +/- 10 meters. The M249 is not bad as long as it is not brand new and has just a taste of carbon left on it. The M240 is a fine weapon worthy of any mans admiration.

And the M40 is The Right Hand.


*fine print*- actual cash value of advice valued at 0.000001 of a cent.

I've been told by many who have served "If yer a soldier and yer not complaining, yer not a good soldier. Complaining is mandatory, per the field manual." <grins>

I don't know that this story contains anything new.

Its all a trade off - a jammed firearm becomes a throwing weapon (M16) and you can't miss fast enuf to win (AK47)

Perhaps they could back off slightly on the tightness of the tolerances on the M16, AND / OR start issuing piston driven M16's.

But I don't know that this story tells us anything we didn't already know.

Sounds like <gasp> the media sensationalizing another story for hype. I, for one, am shocked.

This might explain a few things
Interesting read. Basic gist is that the shorter length from chamber to gas port in teh carbine as compared to rifle is largely to blame for higher pressures and more failures.

They recommend as follows:

1. Reduce the diameter of the gas port to reduce high pressure gas flow to the carrier. This can render the mechanism somewhat more prone to powering problems than the larger gas port of the rifle

3. Shift the gas port. ArmaLite has shifted its carbines gas port two inches forward compared to the M4 Carbine. Since the commercial minimum barrel length is set by law, this change serves reduce the gas pressure, delay its transmission to the carrier group, and reduces the length of barrel (and thus gas pulse duration) beyond the gas port. This change is easy in a commercial setting but has logistics implications for the military.
But in my experience, the problem with 11.5 carbines is TOO LITTLE gas pressure to cycle the action, typically corrected by OPENING UP the gas port.

Armalites article seems to contradict itself, to my reading.
