Senators diverted $2.6 billion in funds in a defense spending bill to pet projects largely at the expense of accounts that pay for fuel, ammunition and training for U.S. troops, including those fighting wars in Iraq and Afghanistan, according to an analysis.

Lance, I think correctly, pointed out to me that this attitude of cutting defense spending to the max, probably guarantees that the M4 and M16 are not going anywhere anytime soon.

Many thanks to Daniel Watters for the link.

The M4 Carbine

The AP infers that the barrels of many of the weapons were getting white hot. From the AP article:

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.

There is only one reference to a gun getting white hot in the draft report, and it is a SAW not a M4 Carbine:

Specialist Bogar fired approximately six hundred rounds at a cyclic rate of fire from his SAW when that weapon became overheated, and eventually jammed the bolt forward. Specialist Stafford noted, “Bogar was still in our hole firing quite a bit. Then Bogar’s SAW jammed. Basically it just got way overheated, because he opened the feed tray cover and I remember him trying to get it open and it just looked like the bolt had welded itself inside the chamber. His barrel was just white hot.”

In fact, it is not even possible that an M4 barrel can heat up to the point of being white hot. M4 barrels are made from Alloy Steel 4150. The melting point of this steel is 1426 degrees Celsius. For steel to go white, it needs to be over 1400 degrees Celsius.

The Ground Precautionary Message ACALA #97-03¹, from November 1996, clearly states that if an M4 barrel reaches just 737 degrees Celcius, the barrel will be weaked to the point where burst.

(3) BURST BARRELS RESULT WHEN THE WEAPONS ARE FIRED UNDER VERY EXTREME FIRING SCHEDULES AND THE BARREL TEMPERATURE EXCEEDS 1360 DEGREES FAHRENHEIT. WHEN THE BARREL REACHES THESE EXTREME TEMPERATURES, THE BARREL STEEL WEAKENS TO THE POINT THAT THE HIGH PRESSURE GASES BURST THROUGH THE SIDE OF THE BARREL APPROXIMATELY 4 INCHES IN FRONT OF THE CHAMBER. THIS CONDITION CAN RESULT IN SERIOUS INJURY.

You are not going to see an M4 barrel white hot because by that point it would have exploded!

The AP also infers that the M4 Carbine is designed to handle a high rate of fire

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.

This is also not true. From the Ground Precautionary Message[^1]:

(B) FIRING 140 ROUNDS, RAPIDLY AND CONTINUOUSLY, WILL RAISE THE TEMPERATURE OF THE BARREL TO THE COOK-OFF POINT. AT THIS TEMPERATURE, ANY LIVE ROUND REMAINING IN THE CHAMBER FOR ANY REASON MAY COOK-OFF (DETONATE) IN AS SHORT A PERIOD AS 10 SECONDS.

...

(D) SUSTAINED RATE OF FIRE FOR THE M16 SERIES RIFLES AND M4 SERIES CARBINES IS 12-15 ROUNDS PER MINUTE. THIS IS THE ACTUAL RATE OF FIRE THAT A WEAPON CAN CONTINUE TO BE FIRED FOR AN Indefinite LENGTH OF TIME WITHOUT SERIOUS OVERHEATING.

No operator should empty more than 4 magazines rapidly. The AP quotes the draft report:

My weapon was overheating. 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.”

I sympathize with the solider and would not dare to presume to question his actions in combat. He did what he had to do in the heat of the moment, but I cannot think of any current weapon in the M4 class that can sustain continuous fire. To make such a weapon it would need to have a heavy quick change barrel and maybe also include a heat sink. I doubt any soldiers will want to trade in their M4 for a heavy automatic rifle.

Many thanks to Jay, aka. jdun1911, for his research into this controversy. He should get all the credit for this blog post.

UPDATE: I just want to clarify a point mentioned by commenters below. If the solider fired his 12 magazines evenly over a 30 minute period he should have had no overheating problems (assuming the Army GPM info is correct). What we do not know is the period of continuous fire. As Bram, who has seen combat, said "Time moves very differently while under fire. It’s impossible to judge how fast those soldiers were actually firing.".

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.

...

"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."

Snowflakes In Hell, via Michael Bane's blog, correctly points out that assault rifles are not machine guns:

No assault rifle is going to stand up to sustained automatic fire. They aren’t machine guns, and even a machine gun needs to have its barrel changed out if it’s been firing a lot.

The M4 has a very short 14.5" barrel and a relatively lightweight barrel profile. This allows the barrel to heat up much faster than a longer and heavier rifle or machine gun barrel. When the barrel of a closed-bolt gun gets very hot, cook-offs,when a round is ignited from the heat in the chamber, become a significant problem ... not to mention the fact that a soldier cannot fire a gun that is to hot to hold!

The Marines have been criticized by many for their plans to introduce an Infantry Automatic Rifle (IAR) into the mix of weapons issued to their troops. The IAR is not intended to replace the SAW but would be deployed alongside it, giving some riflemen a light weight weapon that can sustain automatic fire.

FN IAR. Switches from closed-bolt to open-bolt when automatically when barrel temperature increases.

The Army would do well to look into the concept.

At the end of last year the Marines announced they were awarding contracts for the development of IAR prototypes to Colt, H&K and FN. Since then I have heard nothing about the IAR.

There are discussions about the M4 failure at Wanat over at Snowflakes In Hell, via Michael Bane's blog and SaysUncle.

Many thanks to Jerry, Caedis, Lee and Lance for emailing me links about this story.

Surefire snuck out two new 5.56mm suppressors at Modern Day Marine Expo. The Mini and the Micro are stubby little suckers that add barely 3.6 and 2.6 inches to a weapon’s muzzle but cut down weapon signature and improve unit communication.

There is nothing magical about suppressors and they are bound to the same laws of physics as everything else. While suppressor manufactures are continuously tweaking their cans in order to maximize the sound reduction vs. weight / size ratio, ultimately if you shrink a suppressor you will reduce its effectiveness.

I doubt these will be sold to civilians. I cannot think of a single good reason why a civilian would want to purchase one of these particular suppressors, when a suppressor a few inches longer will give much better performance.

UPDATE: I may have come across as anti-suppressor. I am not. I own two and hope to buy a third within a year. They are incredibly useful and there is no reason why civilian sales should be restricted. But these particular suppressors are tiny - smaller than my .22 Rimfire suppressor - the sound reduction would be minimal. I would call it a "sound reducer" rather than a "sound suppressor". What I meant to say is that I cannot think why a civilian would pay for these particular suppressors.

Many thanks to Jesse for the link.

.22's: HK has licensed Umarex to produce .22-cal versions of the 416, MP5, and MP7. At least some of these should be on display by SHOT Show in January 2010. It has not yet been determined which models will be released first.

At this years SHOT Show Umarex unveiled a licensed rifle patterned after and branded the Colt M4.

Benelli M4 with Extended Charging handle.

On Point are selling them for $30.

Two years ago when I was in Iraq, I noticed there were essentially two different primary infantry weapons (the M16 automatic rifle and the also-automatic M4 carbine) carried by America’s two primary ground forces — the U.S. Marine Corps and the U.S. Army.

Marines for the most part were carrying the M16. The Army on the other hand was primarily carrying the M4: a shorter, lighter version of the M16 with a collapsible-stock.

Hat Tip: Say Uncle

Two readers emailed me saying that many of the weapons I mentioned in my 5 Weapons that should’ve been in Transformers 2 post were used in new hit sci-fi movie District 9. I was considering seeing the movie, but after hearing this I decided I had to go. It was fantastic! Despite being a low budget production, they must have hired a very competent weapons consultant. The weapons used were appropriate for the task at hand and were used correctly, something few action, or even historical, movies do right.

Where can I buy this target?

There are three main human factions in the movie. The Multi-National United is organization styled after the UN. The Mercenaries (I can’t remember what they are called in the movie) are private military contractors styled after the likes of Blackwater (Xe). The Gangsters live among the aliens and are involved in the arms trade.

The movie is set in South Africa so it is no surprise that many of the weapons used in the movie are weapons produced by the South African defense industry.

Multi-National United (MNU)

Vektor CR-21 – This is the “white” gun used by the MNU. The 5.56 mm CR-21 is a bullpup version of the Vektor R4. The R4 is the South African licensed-built version of the Israeli Galil (an AK-47 derivative).

CR-21

R1 (FN FAL) – The R1 was the South African licensed-built FN FAL. In the movie it is used by airborne snipers.

R1 / FN FAL

Unknown Pump Action Shotgun – A pump action shotgun is used by a minor character. I could not identify it.

Mercenaries

Vektor R5 – This is the carbine version of the Vektor R4 rifle. The R5 has a 13.1″ barrel.

Vektor R5.

Colt M4 with M203 – Some troops appear to be using the M4 Carbine and M203 grenade launcher.

Colt M4/M203

FN Minimi – Better known as the M249 Squad Automatic Weapon (SAW).

FN Minimi

PMP Neopup PAW – I am pretty sure this awesome semi-automatic grenade launcher was used briefly.

Denel NTW-20 – This South African made 20mm rifle was used too good effect.

Unknown Machine Pistol – A machine pistol or submachine gun was used in one scene, but I could not identify it. UPDATE: Commenters point out that it was the BXP.

Unknown Pistol – I could not identify the pistols carried by the mercs. UPDATE: IMFDB says it was a Beretta 92FS.

Gangsters

AK-47 – Not introduction needed.

RPG-7 – Again, no introduction need. Used realistically in the film.

RPG-7

Milkor MGL – I was surprised to see the gangsters packing this. I only saw it in one scene.

M1911 pistol – I am pretty sure a 1911 clone is used by one of the gangsters.

While watching the movie I tried to keep track of what guns they were using. I probably missed many and I had trouble identifying some. Please post a comment below if noticed any mistakes or omissions I have made or identify any of the unknown weapons listed.

Thanks to Cory and Raymond for their emails regarding the movie weapons.

UPDATE: More info at IMFDB (Spoiler alert).

Benelli MR1 Carbine

The MR1 Carbine is the civilian version of the Beretta Rx4 Storm (which never took off). Benelli, a subsidiary of Beretta, designed the ARGO gas system used by the MR1/Rx4 and manufactured both the MR1 and the Rx4 Storm.

Beretta RX4 Storm with accessories. The collapsible stock is not available currently on the RX4.

What differentiates the MR1 from other 5.56mm rifles is the gas system it uses. Originally the Auto-Regulating Gas System (ARGO) was designed for the Benelli M4 Super 90, better known by its US Military designation, the M1014 Joint Service Combat Shotgun. Benelli then adapted the system for their ARGO line of hunting rifles (branded the R1 in the United States). In 2005 the Beretta Rx4 Storm, a tactical version of the ARGO rifle, was introduced and marketed to law enforcement. As far as I know the Rx4 has never been available in a select fire variant but they decided to market it to civilians as the Benelli MR1.

Benelli M4 Super 90 / M1014

Benelli ARGO EL

The ARGO gas system has an interesting short stroke piston design. Gas is trapped very close to the chamber. The high pressure gas ensures reliable cycling regardless of ammunition. This means that it can cycle any shotgun shells, regardless of the load. For a rifle it means the barrel can be very short and a suppressor could be fitted without any cycling issues. This gun is just asking to be converted into a Short Barreled Rifle!

The gas is then fed into an expansion chamber. The pressure in the chamber drives the piston assembly, which has dual rods. The high pressure is regulated by a release value. These diagrams should illustrate how the system works.

The receiver is made of aluminum, it is fully compatible with AR-15 magazines (including the 100 round drums) and, like all Benelli shotguns and rifles, the main spring is placed inside the butt stock - meaning a folding stock is not an option, although hopefully an M1014 folding stock will be made available.

MR1 Specifications:

Caliber: 5.56mm NATO / .223 Rem. Barrel: 16". Hard chrome lined. 1:9 twist. Rear Sights: Military-style Aperture Weight: 7.9 lbs.

The MSRP is $1299. I think they have priced it right. Although not cheap, and they can do better than the one five round magazine they ship with it, I doubt they could sell it much cheaper.

He says that the gun market is cooling but S&W’s M&P rifles and tactical rifles are selling well. I do not dispute that S&W is doing well, but I find it hard to believe S&W, or Ruger, will be able to maintain their current stock prices. Both stocks have more than doubled since February courtesy of the gun buying frenzy.

Golden mentions the M4 competition. I expect they will have sometime more interesting up their sleeve than the M&P4, a pretty standard direct gas impingement M4 clone, which the Military Times reported a while back that S&W would be entering.

As of July 1, the Army has taken control of the design rights to the M4 carbine from its sole maker, Colt Defense LLC. Translation: With an uncertain budget looming, the service is free to give other gun companies a crack at a carbine contract.

The transition of ownership of the M4 technical data package marks the end of an era and Colt’s exclusive status as the only manufacturer of the M4 for the U.S. military for the past 15 years.

What does this mean for Colt as a company? Not a lot. They will continue to be a supplier and will probably be able to manufacture the M4 cheaper than competitors when / if any more M4 carbines are purchased.

Over at Snowflakes in Hell Daniel E. Watters, an expert, said that the Army will still have to pay in royalties to Colt for every non-Colt M4 purchased. The technical specs are owned by Colt. Anyone wanting to supply M4s to overseas customers will need to get a license from Colt.

Colt has a few different next-gen carbines ready for the carbine competition later this year which could result in a selection of an M4 replacement.

There is also a discussion about this at Gun Pundit

“FREEFALLE7″, a Ranger Instructor, posted the above photo at AR15.com. A student, on arrival at the Swamp phase of Ranger School, showed him his M4 and said “my barrel fell off”. His punishment for not telling an instructor at the Mountain phase (the previous phase) about the broken M4 was to be given a M240, which weights 27 lbs, as a replacement.

Keith J came up with a plausible theory of how this happened

Salt water in the threads. Steel rusts. Steel in contact with aluminum. Aluminum then oxidizes, reducing the rust to iron dust. Joint remains tight until it is abused, then it just falls apart.

This all started when the barrel was installed and it was tightened a bit too much, causing the anodizing to crack

Of course this would have happened over a long period of time and use.

Thanks to Jay for the link.

The Iraqi Army are slowing migrating from AK-47s to M16s and it looks like their Special Forces are getting M4 carbines for good measure. I am pleased to see they are getting the equipment they need.

The rifle seems to be well received by Canadian shooters, although the finish is said be be poor. Of the Norinco manufactured firearms I have seen, they tend to be poorly finished. The badly scratched finish can be seen in this photo:

This video shows the firearm being used (iron sights and Magpul stock has been installed):

LeverArms.com are selling it for C$899.00, which seems like a good price for a M4 clone, although I am not sure what M4 AR-15s normally sell for in Canada. Canada is likely the only country where it is being sold to civilians.

Thanks to Dennis for information about the rifle.

According to Wikipedia:

This variant introduced in the year 2006 in several Defense expos worldwide, including the MILIPOL, is a copy of the American M4A1 assault carbine. It features a telescoping stock, a removable carrying handle mounted on a Picatinny rail, and a 368,3 millimetres (14,5 inches) barrel. The CQ Type A carbine variant is claimed to be able to stabilize both M193 “Ball” and SS-109/M-885 variants of the 5.56 mm cartridge, as would be expected from a rifle with a 1:9 barrel rifling twist. It will quickly accept the installation of grenade launchers due to the quick attachment/detachment handguard design and to the step-cut barrel.

To clear up “125″ issues and confusion the A3 varient is to be upgraded to allow the firing of GLA and underslung shot gun attachment with the trigger finger. There is much speculation on INF 2012 weapon systems and the steyr will look marketly different. What is concrete is that what changes happen to the weapons system the it must have the same range or better and must not be any heavier than current weight with modifications. There is a photo around of an ugly australian modified A3, this is not the new rifle and was a test bed system and was a demo only. The ADF rumour mill is leaning more to the AUG A4 design as now Australia owns the rights of all world wide styer production and also pattened designs from Austria.

I had not idea that the A4 existed. I did some Googling and found some photos in a brochure from ADI, the Australian arms and ammunition manufacturer. They may be the “test” A4 that Matt mentioned in Matt’s comment.

I think it’s a pretty ugly design. It looks like someone attacked an AUG with a hacksaw, screwdriver and a few picatinny rails. Especially in contrast to the AUG A3 (from steyr-arms.at):

Where is the grenade launcher trigger?

I would be surprised if the Australians upgrade their A1/A2 AUGs to use the M203 when the M320 will go into production later this year (according to Wikipedia).

M4 with M320

Blackwater BW-15

The public seemed poised to receive Blackwater’s new BW15 rifle after handling two samples that featured the Blackwater logo. “We’ve had a lot of people ask how they can get one, said Alan Alligood, Blackwater armorer.” Blackwater’s highly trained and ex-perienced armorers take the basic M4 to the next level by offering custom rifles that are built exactly to the customer’s wishes.

“We have a hard time helping people understand that we are not offering a line or series of guns. We build want they want. Each one may be different,” says Armory Chief Bill Kirkland. In a business where the firearms industry is saturated with variations and types of ARs, the BW15 represents a truly unique approach. The rifles can only be ordered through the Blackwater Armory, making them very exclusive and highly desirable.

I have emailed Blackwater for more information … lets see if they respond.

“I don’t think we need an unhealthy, discordant debate over the current carbine because I don’t think the current carbine is a long-lived solution anyway. However, the M4 carbine has been continuously improved. It has 68 substantial engineering design changes and about 380 total engineering design changes, so it’s become a modular system. It’s very accurate, it’s the most accurate of the carbines, it’s the lightest of the carbines, and it’s the shortest of the carbines. We’re very pleased with it, and we expect it to be the Army’s carbine of record, for a little while.”

Some interesting suppressed AKs, they look like AK-103’s but could be something else, and what is probably a Norinco CQ (M16A1 clone) or CQ-M4 (you guessed it, an M4 clone).

Although, I wouldn’t be surprised if these were airsofters (btw, I have nothing against airsoft).

One of the upgrades that may be coming in the future is a more reliable magazine. The test revealed that 239 of the 882 stoppages M4 suffered were magazine-related.

The hope is that upgrades, such as stronger springs, will increase the magazine’s ability to feed rounds more effectively, Radcliffe said. If all goes well in testing, the improved magazines could be ready by next spring.

Another upgrade under consideration is a “hammer-forged” barrel, Brown said.

I didn’t think that they were actually planning on replacing the M4 when they announced the testing. Even without magazine stoppages the M4 performed very badly.

DID has a very comprehensive article

“Even with extreme dust test III’s 98.6 percent success rate there was a total of 863 class 1 and 2 weapon/magazine stoppages with 19 class 3 stoppages. During extreme dust test II conducted during the summer, there were 296 total class 1 and 2 stoppages and 11 class 3 stoppages.

A class 1 stoppage is one a Soldier can clear within 10 seconds; a class 2 stoppage is one a Soldier can clear, but requires more than 10 seconds; and, class 3 is a stoppage that requires an armorer to clear.”

DID will simply point out that 10 seconds can be a rather fatally long time when people are shooting at you, and at your friends. So, what happens when the Extreme Dust Test III stoppages are broken out by weapon?

The M4 Carbine is the Army’s existing weapon.

* 882 jams, 1 jam every 68 rounds, again using heavy lubrication. In addition all 10 of the M4 barrels needed to be replaced, and a number of their parts were replaced during the test. None of the cold hammer forged HK416 and XM-8 barrels needed replacement.

The HK416 is a modified M4 carbine, which can be and has been converted from existing rifles. Used by US Special Forces.

* 233 jams, 1 jam every 257 rounds, 3.77x more reliable than the M4.

FN SCAR is US special Forces’ new weapon, designed by SOSOCM. It just went into production in late 2007.

* 226 jams, 1 jam every 265 rounds, 3.85x more reliable than the M4

XM-8 is a developmental rifle. It’s an advanced version of HK’s G36, a rifle in wide use by many NATO armies. The US Army cancelled the XM-8 weapons family 2 years ago.

* 127 jams, I jam every 472 rounds, 6.95x more reliable than the M4.

Weapons officials at the Army Test and Evaluation Command at Aberdeen Proving Ground, Md., exposed Colt Defense LLC’s M4, along with the Heckler & Koch XM8, FNH USA’s Special Operations Forces Combat Assault Rifle and the H&K 416 to sandstorm conditions from late September to late November, firing 6,000 rounds through each test weapon.

When the test was completed, ATEC officials found that the M4 performed “significantly worse” than the other three weapons, sources told Army Times.

Officials tested 10 each of the four carbine models, firing a total of 60,000 rounds per model. Here’s how they ranked, according to the total number of times each model stopped firing:

* XM8: 127 stoppages.
* MK16 SCAR Light: 226 stoppages.
* 416: 233 stoppages.
* M4: 882 stoppages.

The results of the test were “a wake-up call,” but Army officials continue to stand by the current carbine, said Brig. Gen. Mark Brown, commander of Program Executive Office Soldier, the command that is responsible for equipping soldiers.

You can bet H&K, FN and Magpul are happy about these results!

Hat Tip: Murdoc Online

The Deputy Prime Minister has said a Malaysian company, SME Ordnance (SMEO), has a license to manufacture the M4 for use locally and possibly for export in the future.

“We took this decision as we want to enable our soldiers to be soldiers of the future, equipped with the latest modern technology”

Interesting. I don’t think Colt will allow export to North America. Export will probably be limited to South East Asian countries.

This is what I came up with (click the image to increase the size)

Some of the countries, such as the UK, only use M16/M4/AR-15/C7/C8 rifles for their special forces. Presumably because the AR-15 platform has no end of customizations available.

Here is a complete list of countries (from the Colt website. The above map is more detailed than the Colt map):

Argentina, Australia, The Bahamas, Bahrain, Barbados, Belize, Bolivia, Botswana, Bosnia and Hercegovina, Brazil, Brunei, Burma, Cambodia, Cameroon, Canada, Chile, Colombia, Congo, Costa Rica, Denmark, Dominican Republic, Egypt, East Timor, Estonia, Fiji, France, Germany, Ghana, Greece, Grenada, Haiti, Honduras, India, Indonesia, Iran, Iraq ,Ireland, Israel, Japan, Jordan, Jamaica, Kuwait, Lebanon, Lesotho, Liberia, Maldives, Malaysia, Mexico, Morocco, Nepal, New Zealand, Norway, Laos, Nigeria, Netherlands, Oman,Pakistan, Panama, Philippines, Portugal, Qatar, Saudi Arabia, Singapore, South Korea, Spain, Sri Lanka, Taiwan, Thailand, Tunisia, Turkey, United Arab Emirates, United Kingdom, Uruguay, Vietnam and Venezuela.

UPDATE

Added Georgia, who are adopting the M4, and Afghanistan, who have been given C7 rifles.

Delta Force worked with a gun maker to come up with a better weapon. The 416 is now considered in many circles to be the best carbine in the world, but the regular Army is sticking with the M4 and M16.

Members of the elite unit linked up with German arms maker Heckler & Koch, which replaced the M4’s gas system with one that experts say significantly reduces malfunctions while increasing parts life. After exhaustive tests with the help of Delta, the H&K 416 was ready in 2004.

Members of the elite commando unit – formally known as 1st Special Forces Operational Detachment-Delta – have been carrying it in combat ever since.

The 416 is now considered in many circles to be the best carbine in the world – a weapon that combines the solid handling, accuracy and familiarity of the M4 with the famed dependability of the rugged AK47.

For the foreseeable future, however, the Army is sticking with the M4 and M16 for regular forces.
