I searched on about 10 different possible topic titles and found nothing. At the risk of a major dupe here's a link to an M4 failure article with vids

M4 Failures

Some beta mags would have really sped up the process eh?

So the CAR government profile barrels aren't as thick as the M4 barrels that I can get for 20$ more?

This is not news.  The SOCOM barrel was developed for a reason.  Should everyine in .mil lug one around?
1/15/2010 11:10:51 AM EDT
[#4]
what were they developed for, other than mounting a grenade launcher? and would the M4 barrel suit me, a civilian, better than a government-profile barrel?

For this, I think the 'testing' now in progress in several of the world's nastiest shit-holes should be conclusive; either the platform is adequately reliable or it isn't. If it isn't, they should make improvements/revisions as needed and get them to the field while they look for the next generation of small arms. All this has basically nothing to do with our semi-automatic civilian guns where the D.I. system and 'pencil' barrel are more than adequate, providing all the benefits of the AR design.


No real need for it, as pointed out the gun can go longer than ammo is carried for it, no one does back to back dumps of mags like that.  Also the standard M4 at 3rd burst will go much long than a old style M4A1 with a non-SOCOM barrel.  The three round burst doubles the amount of time required to get off a magazine, so it would increase the time and number of rounds to failure.

+1 ....never designed with the intent to do what the video is illustrating.  It might make an interesting tool in showing soldiers the limitations of the M4A1 in the suppressive fire roll,  Put that many magazines through an AK and its handguard will go up in flames too.
+1 to both

Really? I would think with all that heat focused around the gas block it would have failed faster, provided the same barrel was used.

Really?  Don't think a piston system would fail under that kind of stress?  You're smokin' something.

Having said that, this was a brutal torture test.... and the M4 performed REMARKABLY well.

I didn't know the M4 was also suppose to be a SAW?


They want everything. They want a carbine to be a an all out machine gun. The whole idea behind the M4 carbine was smaller size, less weight. HBAR it and you defeat the purpose. It's bad enough all the crap that gets put on rifles these days - make it an HBAR and now they'll have themselves 12-13lb "carbines" .....lol.


If I am going to carry anything that heavy, it will be an AK or move up to a .308. The whole idea behind the entire AR-15 concept, from gas system, to action, to mags to ammo...the whole 9 yards...all based on weight savings. That has been long forgotten.


Remember, ounces become pounds and pounds become pain.




It adds five ounces.

“We have to get all of the services to buy in, but it adds five ounces in weight and doubles your sustained rate of fire.”

Anyone else thing the rate of fire progressively decreases in the second video.  It's kind of hard to tell for sure after watching 4+ minutes of sustained automatic fire.

If anything the second test shows what a well built rifle the M4 is!!!

Hell I'd say that about the first video too.

If you have to fire 19 mags on full auto as fast as you fucking can, you're a in a world of hurt.

Standard M4's can't even fire that fast since they can't fire full auto, only 3-round bursts.

Why was the guy loading the magazines like a total spaz?  Push the button, drop the mag, load a fresh one.  3 steps.  Four, if you include the charging handle.  But he was jumping around and loading the magazines like he had ants in his pants.  


Could have been because the charging handle, or the whole rifle, was too hot to touch.  I was surprised he wasn't wearing gloves in the first video.

IDK man. I have fired a few F/A M4's some people allowed me to shoot & they didn't smoke or get that hot after 4 -5 mag dumps or a full dump of a few Beta C mags.

A hand held infantry weapon was never designed to be used like a heavy (or light for that matter) machine gun. This comment to the article I found a bit strange, chiefly his reference to the Alamo (I'm a Texan of course)

How much sustained fire could you get from muzzle loading muskets and rifles? Actually the Mexicans were over the walls in the first 30 minutes and the battle was over after an hour and half. Just nitpicking I know


Seriously.  That's pretty funny stuff.

The government never ceases to amaze me. I wonder what prompted this. Did any of our men get into sustained fire fights requiring full auto fire of 300-500 rounds in a few minutes? Or was it more of an issue of fatigue strength with the lighter barrels?

Regardless, I place my bets that more rounds could have been shot through both barrels had the handguards been a Larue or Knight's URX or if the upper was monolithic with a barrel nut acting as a way to transfer heat away from the barrel more efficiently. M4 handguards shield heat from the user's hands. They do not help the barrel cool if I'm not mistakened.  

And by the way, I bet 20 bucks that most AR-15.com members could reload and shoot faster than the guy in that video

Edited to add: I'm a dumbass. I should have read the whole article. They are referring to this battle: http://www.nytimes.com/2009/10/03/world/asia/03battle.html?_r=1. I hate to be an armchair civilian, but I think had someone like Pat Rogers or Chris Costa trained these troops for a week on how to shoot their M4s, I don't think barrel overheating would have been an issue. Of course, maybe if I saw 200 Taliban coming at me from over a hilltop, I'd freak out and fire full auto mag dumps as well.

They are good trainers, but the type of training they do is not all that applicable to that type of circumstance.  Most civilian shoot revolves around close shooting, it a little less than applicable in platoon on company sized fire fight where your belt feed weapons and supporting arms are your biggest killers.

What kind of barrel can only handle 535 rounds of sustained full auto fire?

Where was the artillery?  Where was the CAS?  Where were the heavy weapons?  M-2's and Mk19's?  The M-4 is an assault rifle, intended to be a lightweight weapon, not a machine gun designed for suppressing fire.  Loading up soldiers with weight to counter increasingly unrealistic scenarios isn't a good idea, no matter how well intentioned.  This goes for weapons, armor, and anything else.

Of course, I'm just an armchair commando too, so all that and $2.50 will buy you a cup of coffee.
