An M4 – or is it?
(click to view full)
The 5.56mm M-16 has been the USA’s primary battle rifle since the Vietnam war, undergoing changes into progressive versions like the M16A4 widely fielded by the US Marine Corps, “Commando” carbine versions, etc. The M4 Carbine is the latest member of the M16 family, offering a shorter weapon more suited to close-quarters battle, or to units who would find a full-length rifle too bulky.
In 2006 an Army solicitation for competitive procurement of 5.56mm carbine designs was withdrawn, once sole-source incumbent Colt dropped its prices. The DoD’s Inspector General weighed in with a critical report, but the Army dissented, defending its practices as a sound negotiating approach that saved the taxpayers money. As it turns out, there’s a sequel. A major sequel that has only grown bigger with time.
The M4/M16 family is both praised and criticized for its current performance in the field. In recent years, the M4 finished dead last in a sandstorm reliability test, against 3 competitors that include a convertible M4 variant. Worse, the 4th place M4 had over 3.5x more jams than the 3rd place finisher. Was that a blip in M4 buys, or a breaking point? The Army moved forward with an “Individual Carbine” competition, but as the results started to show the M4 again lagging – even with ammunition changed to a round specially formulated to make the M4 shine – the Army abruptly stopped the process once again, stating that the performance superiority of the competing gun was not better to a degree making it worthwhile. The Army stated after the tests that only a result that was twice as good as the existing gun’s performance would signify an actionable performance difference.
More recently, the Marines have considered adding
various after-market upgrades to the platform in order to increase accuracy, learning from the private sector and competitive shooting circuit what appears to be providing the best bang.
The M4 Carbine

It seemed like a routine request. Order more M4 carbines for US forces in the FY 2007 supplemental, FY 2008 budget, and FY 2008 supplemental funding bills. It has turned into anything but a routine exercise, however – with serving soldiers, journalists, and Senators casting a very critical eye on the effort and the rifle, and demanding open competition. With requests amounting to $375 million for weapons and $150 million in accessories, they say, the Army’s proposal amounts to an effort to replace the M16 as the USA’s primary battle rifle – using specifications that are around 15 years old, without a competition, and without considering whether better 5.56 mm alternatives might be available off the shelf.
The M4 offers a collapsible buttstock, flat-top upper receiver assembly, a U-shaped handle-rear sight assembly that could be removed, and assortment of mounting rails for easy customization with a variety of sight, flashlight, grenade launchers, shotgun attachments, etc. It achieves approximately 85% commonality with the M16, and has become a popular weapon. It has a reputation for lightness, customizability, and, compared to its most frequent rival the AK-47, a reputation for accuracy as well. The carbine’s reputation for fast-point close-quarters fire remains its most prominent feature, however. After Action Reviews done by the Marines after the early phases of Operation Iraqi Freedom revealed that urban warfare scenarios made employment of the M16A2 difficult in some situations; Marines were picking up short AK-47s with folding butt-stocks, or scrounging pistols for use inside buildings.
Like its predecessor the M16, the M4 also has a reputation as an excellent weapon – if you can maintain it. Failure to maintain the weapon meticulously can lead to jams, especially in sandy or dusty environments. Kalashnikovs may not have a reputation for accuracy, or lightness – but they do have a well-earned reputation for being able to take amazing amounts of abuse, without maintenance, and still fire reliably. The Israeli “Galil” applied these lessons in 5.56mm caliber, and earned a similar reputation. Colt’s M16 and M4 have never done so.
The original order for the M4 Carbine in the mid-1990s was a small-scale order, for a specifically requested derivative of the Army’s primary battle rifle, to equip units who would otherwise have relied on less accurate 9mm submachine guns. As such, its direct development and sole-source contract status raised little fuss. Subsequent contracts also raised little scrutiny.
So, what changed?
1. Extended combat in dusty, sandy environments that highlighted the weapon’s weak points as well as its comparative strengths, leading to escalating volumes of complaints;
2. The emergence of alternatives that preserve those strengths, while addressing those weak points;
3. The scale of the current request for funding.

XM29 OICW Prototype

There have been sporadic attempts to field more modern weapons during its tenure, including the unwieldy 20-or-so pound, 2 barrel, “someone watched Predator too many times” XM-29 OICW, and more recently the aborted contract for the G36-derived XM-8 weapon family from Heckler & Koch. Still, the M4’s designers could never sing B.B. King’s famous tune.
The M16/M4 family has achieved a great deal of success, and garnered many positive reviews for its features and performance. Even its critics acknowledge that it has many positive attributes. The M4 has also attracted criticism – and at least 1 comprehensive fix.
According to briefing documents obtained by Gannett’s Army Times magazine:
“USMC officials said the M4 malfunctioned three times more often than the M16A4 during an assessment conducted in late summer 2002 for Marine Corps Systems Command at Quantico, VA. Malfunctions were broken down into several categories, including “magazine,” “failure to chamber,” “failure to fire,” “failure to extract” and “worn or broken part,” according to the briefing documents. During the comparison, the M4 failed 186 times across those categories over the course of 69,000 rounds fired. The M16A4 failed 61 times during the testing.
The Army conducted a more recent reliability test between October 2005 and April 2006, which included 10 new M16s and 10 new M4s… On average, the new M16s and M4s fired approximately 5,000 rounds between stoppages, according to an Army official who asked that his name not be released.”
In a subsequent letter to the magazine, M4 manufacturer Colt argued that the US Army had disagreed with the USMC study, then added that the Army and Colt had worked to make modifications thereafter in order to address problems found.
Gannett’s Army Times magazine also obtained a copy of Project Manager Soldier’s Weapons Assessment Team’s July 31, 2003, report:
“The executive summary said that M16s and M4s “functioned reliably” in the combat zone as long as “soldiers conducted daily operator maintenance and applied a light coat of lubricant.”
Soldiers had their own comments, however, which were also included in the report and relayed in the magazine article. 3rd ID soldier:
“I know it fires very well and accurate [when] clean. But sometimes it needs to fire dirty well too.”
25th Infantry Division soldier:
“The M4 Weapon in the deserts of Iraq and Afghanistan was quick to malfunction when a little sand got in the weapon. Trying to keep it clean, sand free was impossible while on patrols or firefights.”
82nd Airborne Division soldier:
“The M4 is overall an excellent weapon, however the flaw of its sensitivity to dirt and powder residue needs to be corrected. True to fact, cleaning will help. Daily assigned tasks, and nonregular hours in tactical situations do not always warrant the necessary time required for effective cleaning.”
75th Ranger Regiment member, SOCOM:
“Even with the dust cover closed and magazine in the well, sand gets all inside; on and around the bolt. It still fires, but after a while the sand works its way all through the gun and jams start.”
The 507th Maintenance Company, ambushed outside Nasariyah in 2003 during the opening days of the ground invasion of Iraq, might concur with all of the above. The post-incident report released by the US Army had this to say:
“Dusty, desert conditions do require vigilance in weapons maintenance… However, it is imperative to remember that at the time of the attack, the 507th had spent more than two days on the move, with little rest and time to conduct vehicle repair and recovery operations.”
Even without those extenuating circumstances, however, there have been problems. A December 2006 survey, conducted on behalf of the Army by CNA Corp., conducted over 2,600 interviews with Soldiers returning from combat duty. The M4 received a number of strong requests from M-16 users, who liked its smaller profile. Among M4 users, however, 19% of said they experienced stoppages in combat – and almost 20% of those said they were “unable to engage the target with that weapon during a significant portion of or the entire firefight after performing immediate or remedial action to clear the stoppage.” The report adds that “Those who attached accessories to their weapon were more likely to experience stoppages, regardless of how the accessories were attached [including via official means like rail mounts].” Since “accessories” can include items like night sights, flashlights, etc., their use is not expected to go away any time soon.
US Army Ranger Capt. Nate Self, whose M4 jammed into uselessness during a 2002 firefight after their MH-47 Chinook was shot down in Afghanistan’s Shah-i-kot Mountains, offers another case. He won a Silver Star that day – with another soldier’s gun – and his comments in the Army Times article appear to agree that there is a problem with the current M4 design and specifications.
M4 SOPMOD
(click to view full)
SOCOM appears to agree as well. While US Special Operations Command is moving ahead on their own SCAR rifle program with FN Herstal, they’re also significant users of the M4 Carbine’s SOPMOD version. By the time Capt. Self was fighting of al-Qaeda/Taliban enemies in Afghanistan with a broken weapon, Dellta Force had already turned to Heckler & Koch for a fix that would preserve the M4 but remove its problems. One of which is heat build-up and gas from its operating mechanism that dries out some lubricants, and helps open the way for sand damage.
In response, H&K replaced Colt’s “gas-tube” system with a short-stroke piston system that eliminates carbon blow-back into the chamber, and also reduces the heat problem created by the super-hot gases used to cycle the M4. Other changes were made to the magazine, barrel, etc. The final product was an M4 with a new upper receiver and magazine, plus H&K’s 4-rail system of standard “Picatinny Rails” on the top, bottom, and both sides for easy addition of anything a Special Operator might require.
HK416, labeled
(click to view full)
In exhaustive tests with the help of Delta Force, the upgraded weapon was subjected to mud and dust without maintenance, and fired day after day. Despite this treatment, the rifle showed problems in only 1 of 15,000 rounds – fully 3 times the reliability shown by the M4 in US Army studies. The H&K 416 was declared ready in 2004.
A rifle with everything they loved about the M4, and the fire-no-matter-what toughness of the Kalashnikov, was exactly what the Deltas ordered. SOCOM bought the first 500 weapons right off the assembly line, and its units have been using the weapon in combat ever since. Other Western Special Forces units who liked the M4 Carbine have also purchased HK416s, though H&K declines to name specific countries. US Major Chaz Bowser, who has played a leading role in SOSOCM’s SCAR rifle design program:
HK416: Desert Testing
(click to view full)
“One thing I valued about being the weapons developer for Special Operations is that I could go to Iraq or Afghanistan or anywhere with whatever weapons I wanted to carry. As soon as the H&K 416 was available, it got stuffed into my kit bag and, through test after test, it became my primary carry weapon as a long gun. I had already gotten the data from folks carrying it before me and had determined that it would be foolish to risk my life with a lesser system.”
Actually, they don’t even have to buy the whole gun. Christian Lowe of Military.com reports that:
“In a routine acquisition notice March 23 [2007], a U.S. Special Forces battalion based in Okinawa announced that it is buying 84 upper receiver assemblies for the HK416 to modify their M4 carbines… According to the solicitation for the new upper receiver assemblies, the 416 “allows Soldiers to replace the existing M4 upper receiver with an HK proprietary gas system that does not introduce propellant gases and the associated carbon fouling back into the weapon’s interior. This reduces operator cleaning time, and increases the reliability of the M4 Carbine, particularly in an environment in which sand and dust are prevalent.”
But the US Army won’t consider even this partial replacement option. The Army position was reiterated in a release on April 2/07:
“The M4 Carbine is the Army’s primary individual combat rifle for Infantry, Ranger, and Special Operations forces. Since its introduction in 1991, the M4 carbine has proven its worth on the battlefield because it is accurate, easy to shoot and maintain. The M4’s collapsible stock and shortened barrel make it ideal for Soldiers operating in vehicles or within the confines associated with urban terrain. The M4 has been improved numerous times and employs the most current technology available on any rifle/carbine in general use today.
The M4 is the highest-rated weapon by Soldiers in combat, according to the Directorate of Combat Development, Ft. Benning, Ga. In December 2006, the Center for Naval Analysis conducted a “Soldiers’ Perspective on Small Arms in Combat” survey. Their poll of over 2,600 Soldiers reported overwhelming satisfaction with the M4. The survey included serviceability and usefulness in completing assigned missions in Iraq and Afghanistan.”
The Cry for Competition: How Much Is That HK In the Window?
HK416s
(click to view full)
The HK416 isn’t the only alternative out there by any means – but it has been a catalytic alternative. In an analogous situation, limited USMC deployment of mine-resistant vehicles like Force Protection’s Cougar and Buffalo in Iraq, and the contrast between v-hulled casualties and Hummer casualties, led to a cascade that now looks set to remove the Hummer from a front-line combat role. The technology to deal with insurgencies that used land-mines has been proven for over 30 years – but awareness of that fact didn’t rise within the US military and among its political overseers until an obvious counter-example was fielded. One that demonstrated proven alternatives to the limited options people had previous been shown. Likewise, the use of the high-commonality HK416 has served to sharpen awareness that the M4 might not be the best option on offer for US forces.
Couple that with a major buy that looks set to re-equip large sections of the US military with a new battle rifle, and the question “what if we can do better?” starts to take on real resonance. The Army’s $375 million sole-source carbine procurement, on the basis of specifications that have not been changed to reflect these realities, is starting to raise hackles – and attract a wide spectrum of opponents.
Gannett’s Army Times quoted former Army vice chief of staff Gen. Jack Keane (ret.), who tried at the end of his tenure to update the USA’s infantry rifle with the XM-8 project, as saying:
“We are not saying the [M4 and M16 are] bad,” said “The issue for me is do our soldiers have the best rifle in their hands… The fact of the matter is that technology changes every 10 or 15 years and we should be changing with it. And that has not been our case. We have been sitting on this thing for far too long.”
An aide to Sen. Tom Coburn [R-OK] agreed, and added that the substantial price reduction created by the mere threat of an open competition in 2006 was evidence that Colt had been using its sole-source status to overcharge the government. The Senator has sent a formal letter to the Secretary of the Army requesting an open competition in order to ensure both the best deal, and the best off-the shelf rifle that incorporates modern improvements. The winner could well be Colt, said Coburn’s aide – but they should have to prove it, and earn it. “This is supposed to be a battle rifle.” He said. “We’re supposed to have a rifle that just doesn’t jam.” Impossible, of course – but one that jams far less often, and requires far less maintenance to avoid jams, while offering all of the M4’s compactness and add-on ease… that would represent a significant step forward.
Ironically, even Colt may have a better system ready to go. In a letter to Army Times magazine, Colt COO James R. Battaglini (US Marine Corps Maj. Gen., ret.) said:
“The gas piston system in the H&K 416 is not a new system. Rifles were being designed with these systems in the 1920’s. Colt proposed a piston operated weapon to the Army in the early 1960’s. Today Colt Defense has the ability and expertise to manufacture in great numbers piston system carbines of exceptional quality should the U.S. military services initiate a combat requirement for this type of weapon”
Unfortunately, fighting the Army for improvements is no easy task. Colt CEO William Keys, who is also a retired USMC General, explained out to Army Times that Colt has to build what the US Army asks for, to the Army’s exact specifications:
“If we have a change that we think would help the gun, we go to the Army… which is not an easy process, by the way. We spent 20 years trying to get [an extractor] spring changed. They just said ‘well, this works good enough.’ “
Sen. Coburn’s letter to Secretary of the Army Peter Green took a dim view of this entire situation:
“I am concerned about the Army’s plans to procure nearly a half a million new rifles outside the any competitive procurement process… There is nothing more important to a soldier than their rifle, and there is simply no excuse for not providing our soldiers with the best weapon – not just a weapon that is “good enough”… In the years following the Army’s requirements document [DID: for the M4 in the early 1990s], a number of manufacturers have researched, tested, and fielded weapons which, by all accounts, appear to provide significantly improved reliability. To fail to allow a free and open competition of these operational weapons is unacceptable… I believe the Army needs to rapidly revise its rifle and carbine requirements. Free and open competition will give our troops the best rifle in the world…”
The positions were, and are, clear. The US Army says the M4 isn’t broken, and adds that an Army-wide fix would cost $1 billion. Critics contend that these costs may be exaggerated given some of the potential solutions, and add that an army already planning to spend $525 million to re-equip the force with M4s has a moral and financial imperative to see if a better rifle exists. Meanwhile, calls about the M16/M4 had been coming in from Oklahoma, and other Senators and representatives had also been hearing from constituents on this matter.
By 2007, a second letter from the Senate was likely if the Army dug in its heels – and that letter would have had far more signatures at the bottom. In the end, however, legislative tactics forced the Army’s hand. The issue finally came to a head when Sen. Coburn [R-OK] exercised his ability as a Senator to block nomination of the proposed new Secretary of the Army, until the US Army relented and agreed to testing at the Army’s Aberdeen Test Center in Maryland. Secretary Geren was confirmed shortly thereafter, in July 2007.
The tests were conducted. The M4 finished last. The Army declared that performance to be acceptable. By 2010, however, there were noises about an “Individual Carbine Competition”, which became a full solicitation. A number of firms are lining up to provide new designs for the Army’s next-generation carbine, including Colt. Some of them even offer alternate caliber options that could make a real difference to lethality at range, a serious need in environments like Afghanistan. By August 2011, known competitors and designs included:
Colt: CM901 multicaliber rifle (5.56mm through 7.62mm)
ADCOR: B.E.A.R. Elite (5.56mm)
FN USA: SCAR-16 (5.56mm)
HK USA: HK416 (5.56mm).
Remington: Adaptive Combat Rifle multi-caliber (5.56mm, 6.5mm Grendel, or 6.8mm)
Smith & Wesson was also reported to be entering the competition, but eventually decided not to take part.
The bigger question is whether this competition, like the ones before it, will ultimately prove to be an expensive mirage. As of April 2013, in the words of the old magic 8-ball, “signs point to yes.” Though one could also use “outlook not so good.”
Any Last Words?
G36s: Norwegian
Telemark battalion
by Torgeir Haugaard
(click to view full)
Sgt. Charles Perales of Fort Bragg, NC had this to say in a letter reprinted by Defense News:
“My unit – B Company, 2nd Battalion, 504th Parachute Infantry Regiment – was deployed to Afghanistan from April 2005 to March 2006. While there, we were attached to Special Forces at Camp Tillman on the Afghan border… I saw first-hand what happens when your weapon jams up because of the harsh environments we have to call home there. An 18B weapons sergeant was shot in the face due directly to his weapon jamming. I just can’t believe that after things like this happen, the Army is still buying more M4s.
Why not rotate them like we used to before the war? All rapid-deploying units used to get the new M4, the support units would get the excess M16s and so on. I’m not saying they need to outfit the whole Army with a new weapon, but why not start phasing it in? …Soldiers’ lives are on the line. Why is it a hassle to make an improvement that could save lives?
The M4 isn’t a bad weapon; it just needs improvements. It’s about time people stop fighting to keep things the same and start moving toward a better weapon system.”
The last word will be left to SOCOM’s Major Chaz Bowser:
“We buy new laptop computers every few years across the gamut, so couldn’t we do the same with our single most important piece of military equipment? … Waiting for a leap-ahead technology based on a kinetic energy weapon platform is a waste of time and money, so we need to look at what is out there now… What the Army needs is a weapon that is now ready for prime-time and not a developmental system… The requirement comes from the field, not from an office in some garrison activity, not from some consultant and definitely not from a vendor.
Let’s do this quickly without all the bureaucracy typically associated with change. Find someone in our ranks who can make a decision – who hasn’t floated a retirement resume with a gun company – and make the decision now. Just look how fast we were all issued the ‘highly coveted’ black beret or the digital uniform. Find that recipe card, change out the word ‘Velcro’ with ‘battle rifle’ and that may be a start to finding a solution [DID: which, he acknowledges, could be Colt’s M4 if that’s what the competition shows]. Our men and women deserve much better than we are giving them, and shame on us.”
Updates: The Tests, Reactions, and Subsequent Developments
FY 2012 – 2016
Army looks to cancel Individual Carbine; USMC won’t join IC; Smith & Wesson out – will sell their innovations to law enforcement and civilians.
Remington ACR
(click for video)
January 13/16: Remington has completed its $40.1 million delivery of M4 carbine rifles to the Philippine Army ahead of schedule. Over 56,000 of the rifles have been delivered in total, and will replace the antiquated 1960s era variant of the M-16 currently in use by the PA. Prior to distribution, a third of the new arms will undergo mandatory ballistic testing while the M-16s will be distributed to reservists.
March 16/15: The Army released a Sources Sought notice (W15QKN-15-X-7820), looking for one vendor that can bundle together a series of aftermarket improvements to the M4A1 carbine. The package, to be called the M4A1+, includes increased accuracy, rails, mounting surfaces, neutral, non-black, color, coatings, backup sites and a kitchen sink full of other, smaller improvements.
Feb 18/15: The Marines are considering adding
various after-market upgrades to the platform in order to increase accuracy, learning from the private sector and competitive shooting circuit what appears to be providing the best bang.
June 14/13: The Army excuses their decision to cancel the Individual Carbie competition by saying that none of the candidates met their criteria of 3,592 mean rounds between stoppages, using the new M855A1 Enhanced Performance Round. As a point of comparison, the original requirement for the M4 was 600.
The Army’s PEO Soldier says that SOCOM’s M4A1 achieved 1,691 MRBS, but refuses to release the results of the trials and provide a basis for relative comparison. Military.com.
May 2/13: Military.com reports that the Individual Carbine’s Phase II firing tests are done, but the US Army is about to cancel the Individual Carbine competition, and direct its tiny $49.6 million in FY 2014 to other things. The original plan involved 3 Phase III contracts, and soldier user tests that would include a total of 800,000 rounds fired.
Overall, the budget for new carbines is $300 million through 2018, and the decision on how to proceed reportedly rests with Secretary of the Army John McHugh. This paragraph sums it up best:
“Gun makers involved in the competition said they have heard nothing from the Army about Phase III of the competition. Competitors didn’t want to be named in this story but said they would not be surprised if the effort was canceled because they never believed the Army was serious about replacing the M4 family.”
March 19/13: Inspector General. In testimony before the House Committee on Oversight and Government Reform, the Pentagon’s Inspector General says they’ll audit the Individual Carbine program, as “DoD may not have an established need for this weapon nor developed performance requirements… such as accuracy, reliability, and lethality”.
Aside from the presumptuousness in the wake of incidents like Wanat, they’re also absolutely wrong on a factual level – the IC competition has had those standards for 3 years now. Source.
Aug 1/12: Political. Sen. Tom Coburn [R-OK] delivers a floor speech about the M4 and the Army’s failure to replace it. He reminds the Senate about the dust testing in which the M4 came in last, and points out that the average rifle age is 26 years, compared to 12 years in Germany, or 8 years for US Special Forces. The Army has been able to rush MRAP competitions for much more expensive equipment, but:
…secretary of Army Guerin… assured me that we would have a new competition for a new rifle for our troops. That was 2007. Here we are, six years later, and the army is now telling us we’re going to have a new competition in 2014… Because the guys that are responsible for making the decision on purchasing the rifles are not the guys that are out there on the line. Because if they were, we would have already had this competition…
On July 13, 2008, in the battle of Winot [sic] in Afghanistan, 200 Taliban troops attacked the U.S. troops at a remote outpost in Eastern Afghanistan. The Taliban were able to break through our lines… Believe it or not, do you know what killed most of us? Our own rifles. Practically every one of our dead was found with his m-16 torn down next to him where he had been trying to fix it. That’s occurring now. Except it’s not getting any press.
…You know, a lot of people do a lot of things for our country, but nobody does for our country what the soldier on the frontline does – nobody. Mr. secretary of the Army. This is a moral question. Get the rifle competition going. Members of congress, members of the senate who are on the armed services committee don’t allow this to continue to happen.
Nov 17/11: USMC sticking with M16A4 & M27 IAR. Military.com reports that the USMC has considered the HK416-derived M27 IAR as a future individual weapon, but decided to stick with improvements to the M16A4 rifle for that role.
It also means that the Marines won’t be adopting the winner of the Army’s Individual Carbine competition, which lowers the odds of having IC turn into a contract for a new weapon. HK might still walk away a winner in the USMC, though. The M27 IARs are being evaluated as future substitutes for FN’s M249 5.56mm light machine gun, and have been fielded to Afghanistan in a combat trial.
Nov 10/11: Smith & Wesson out. Military Times’ Gear Scout reports that Smith & Wesson won’t be competing in the Individual Carbine:
“I talked to David Holt, S&W’s VP of Military Programs who confirmed [the M&P4] was S&W’s entry into the U.S. Army’s individual carbine competition. He explained the company’s decision not to compete in the Army’s search for a new carbine… cited the program’s long acquisition timeline as one of the factors that made it difficult for Smith and Wesson to assume the risk of joining the carbine fray… They’ve put a lot of hours into the project and are very proud of the reliability improvement’s [sic] they’ve made over the M4 design. So, the carbine will likely end up for sale on the commercial LE/Gov market…”
FY 2009 – 2011
M4s and M249s fail at the Battle of Wanat; Key “Taking Back the Infantry Half-Kilometer” report leads to caliber questions; SOCOM cancels FN’s 5.56mm SCAR-L; US Army going through the competition motions, slowly, and giving mixed signals.

Aug 8/11: ADCOR. Military.com covers ADCOR’s announced interest in the IC competition, and its B.E.A.R. design. It’s a gas piston system with some clever features for keeping dust out, a free floating barrel, an adjustable cyclical rate, faster and simpler cleaning, and a “forward charging handle” that lets the soldier clear a jammed weapon with their off hand (also present in Remington’s ACR). Military.com | ADCOR page.
June 21/11: Data Rights Issue. Daniel E. Watters of The Gun Zone explains how the Army got here, the deal with Colt, and the difficulty they’ll have getting a new weapon in the Individual Carbine competition. Read “Colt M4 Data Rights & The Individual Carbine Competition.”
June 14/11: M4. FBO.gov releases Presolicitation W56HZV-10-R-0593, covering 70,000 – 100,000 M4 and M4A1 carbines over 5 years. The Government expects to order 25-30% in each of years 1 and 2, and 13-17% in each of years 3 through 5. They’re certainly serious about the M4, if not about its replacement.
The contractor(s) winning the best value competition will also be required to provide ancillary equipment as specified by the contract, and will be paid only for produced items, not for setup and manufacturing costs. Bidding is restricted to firms in the U.S. & its territories, and the carbines will be produced in accordance with the M4/M4A1 Technical Data Package (TDP) and the license agreement between the U.S. Government and Colt Defense, LLC. That TDP is restricted/ export controlled, and requires submission of a Non-Disclosure Agreement. The TDPs will not be available until an NDA is submitted, and an FBO.gov solicitation is issued. Read “Colt M4 Data Rights & The Individual Carbine Competition” for an analysis of how the Army reached this point, and what it could mean in practice.
June 14/11: Competition. Defense Procurement news reports that the US Army still has a 2-track strategy (vid. March 10/10 entry). One is the IC competition. The other involves competing the M4 design, now that the Army and not Colt owns the data rights. Colt has reportedly reacted to the announced Army plans by ramping up their lobbying efforts, so Congress can pressure the Army to keep the program with them.
May 25/11: Lobbying. An Associated Press article lays out the hired lobbyists and political backers for some of the Individual Carbine contenders, while discussing possible offerings. See also Fox News‘ coverage. Contenders, and their lobbyists, include:

April 18/11: Competition. In published responses to questions from industry over Draft RFP W15QKN-11-R-F003, the US Army has laid out a schedule for its “Individual Carbine”. The RFP is expected in May 2011, with Phase 1 evaluations from July to October 2011, and Phase 2 evaluations extending to July 2012. The contracts, if any, would be awarded in October 2012, followed by even more evaluations of the remaining contenders, lasting until March 2013.
While there is no caliber or mechanical type requirement, the Army may not choose to do anything, in the end. It is openly espousing a “dual path” strategy to upgrade existing M4s, even as it launches this competition. Given a long past history of declaring that new designs don’t offer enough benefits over existing M4s to justify a purchase, outside observers can be forgiven any skepticism they may have over the Army’s determination to field anything else when all is said and done.

Jan 31/11: Competition. The US Army issues Draft RFP W15QKN-11-R-F003 for an “Individual Carbine.” In practice, the solicitation announces an Industry Day on March 30/11, and offerors are directed to NOT submit proposals at this time. Interested parties are advised that only firms within the Small Arms Industry will be granted admittance at the Doubletree Hotel Washington DC – Crystal City, and that ITAR export control procedures are in effect.
Col. Doug Tamilio, the service’s project manager for soldier weapons, reportedly said in a statement that “We’re challenging industry to develop the next-generation carbine and we’re looking forward to the results.” On the other hand, there have been previous industry days (vid. 2008), and other next-generation carbines have been shelved in the past, on the nebulous ground of not being enough of an improvement over the M4.

June 25/10: FN SCAR. Military.com reports that SOCOM has decided to cancel further 5.56mm SCAR-L Mk.16 rifle purchases on cost and efficiency grounds, and will probably recall the 850 fielded weapons, rather than continue to support them. SOCOM will be adding to their stock of 750 7.62mm SCAR-H Mk.17 riles, however, and will field an extended SCAR-H Mk.20 with sharpshooter enhancements.

March 10/10: Competition. In testimony before the House Armed Services Subcommittee on Air and Land Forces, senior Army officers state that [PDF]:
“We are currently taking a dual approach to improve the current weapon, the M4, as we move forward with a new carbine requirement. The Project Manager (PM) released a market survey in January 2010, seeking the best industry has to offer for improvements to the current M4. The PM expects to release an RFP soon to compete the upgrade program. Additionally, the Army will conduct a full and open competition to address a new requirement for an individual carbine. Once the Joint Requirements Oversight Council approves the new requirement, the PM will initiate the competition with the release of an RFP for comments from industry. This is the first step in conducting the competition. The Army is working with the other Services in these programs to ensure their requirements are included in our process and they are always invited to participate in the programs’ development and production.”
Jan 12/10: HK. Heckler & Kock announces that they will begin producing civilian variants of the HK416 and the 7.62mm HK417 in a new HK manufacturing facility in Newington, New Hampshire. It’s co-located within an existing 70,000 square foot facility, and would create an American manufacturing base from which to offer military HK416s as well. EVP Wayne Weber of Heckler & Koch USA:
“It is our intention for all U.S. made HK products to equal the quality and reliability of the products made in Germany… By establishing American-based manufacturing, we can compliment our German production and ensure that HK can be more competitive in the U.S. and comply with government contracts requiring U.S. manufacturing. HK products made in the USA will be fully compliant with federal solicitations giving preference to domestically produced products.”

Nov 30/09: Report. US Army TRADOC releases a paper by Major Thomas P. Ehrhart of the Command and General Staff College titled “Increasing Small Arms Lethality in Afghanistan: Taking Back the Infantry Half-Kilometer” [PDF]. It points out that American forces are routinely engaged in Afghan firefights beyond 300 meters, where their weapons are less effective than their opponents. Excerpts:
“Comments from returning non-commissioned officers and officers reveal that about [50%] of engagements occur past 300 meters. The enemy tactics are to engage United States forces from high ground with medium and heavy weapons, often including mortars, knowing that we are restricted by our equipment limitations and the inability of our overburdened soldiers to maneuver at elevations exceeding 6000 feet. Current equipment, training, and doctrine are optimized for engagements under 300 meters and on level terrain.
There are several ways to extend the lethality of the infantry. A more effective 5.56-mm bullet can be designed which provides enhanced terminal performance out to 500 meters. A better option to increase incapacitation is to adopt a larger caliber cartridge, which will function using components of the M16/M4. The 2006 study by the Joint Service Wound Ballistics – Integrated Product Team discovered that the ideal caliber seems to be between 6.5 and 7-mm. This was also the general conclusion of all military ballistics studies since the end of World War I.
The reorganization of the infantry squad in 1960 eliminated the M1D sniper rifle and resulted in the loss of the precision mid-range capability of the infantry squad… All 5.56-mm weapons are most effective when employed within 200 meters due to velocity limitations. Once contact is made, the fight is limited to machine gunners, mortars and designated marksmen. In the table of organization for a light infantry company8 only the six -M240B 7.62-mm machine guns, two- 60-mm mortars and nine designated marksman armed with either 7.62-mm M14 rifles or accurized 5.56-mm M16A4’s rifles are able to effectively engage the enemy. These weapons systems represent 19 percent of the company’s firepower. This means that 81 percent of the company has little effect on the fight. This is unacceptable.”
Reclaiming the Infantry Half-Kilometer
Oct 12/09: Field. The Associated Press reports that M4 carbine and M249 SAW light machine gun failures contributed to the debacle at Wanat, Afghanistan, in which an American outpost was overrun by the Taliban, and to another situation at nearby Kamdesh. An excerpt:
“[Douglas Cubbison of the Army Combat Studies Institute at Fort Leavenworth, KS] study is based on an earlier Army investigation and interviews with Soldiers who survived the attack at Wanat… The Soldiers said their weapons were meticulously cared for and routinely inspected by commanders. But still the weapons had breakdowns… Cubbison acknowledges the high rates of fire during the two-hour battle may have led to the failures. But he says numerous problems occurred relatively early in the engagement.”
Defense Tech adds that:
“Basically, the most damning conclusions are compiled in the recommendations section of the report. There are a few instanced specified in the report of an M4 fouling, and one where the M4 fouled and the Soldier picked up a SAW and that was jammed up as well… Staff Sergeant Phillips poured out fire, as recalled by another Engineer Specialist loading for him, [SSG Phillips] went through three rifles using them until they jammed.”

Sept 17/08: Competition. Military.com’s Christian Lowe reports that that the Army issued a solicitation to industry in August 2008, asking companies to submit proposals that would demonstrate “…improvements in individual weapon performance in the areas of accuracy and dispersion… reliability and durability in all environments, modularity and terminal performance.”
The intervening years have seen a number of new carbine designs hit the market, as well as a number of “personal defense weapons” that attempt to deliver carbine-class firepower in a weapon only slightly larger than a pistol. Most use calibers other than 5.56mm or 9mm, however, which has prevented their adoption for use by pilots, vehicle crew, and other specialists who need an extremely compact weapon. The Army solicitation also asks for ideas on a “subcompact” variant that would fit in this category.
The article quoted Richard Audette, project manager for Soldier weapons at the US Army’s Picatinny Arsenal. The Army is currently working on its carbine requirements document, and is trying to write it in a way that does not exclude other calibers:
“We’re at the point now where we’re going to go out and compete… We’re looking for anyone that has a world-class carbine… We’re interested in any new technologies out there… We want to know about everything that’s out there, regardless of caliber… If you’ve got a 6.8 [mm caliber weapon], we’re interested in that and seeing what that brings to the table.”
What the Army will insist upon, however, is production capacity. Colt can churn out 10,000 M4s per month, and in June 2009 the M4s blueprints will no longer be a Colt exclusive. Experience with ongoing M16 orders suggests that this will expand production capacity, and drive down prices. In contrast, manufacturers of weapons in promising new calibers like 6.8mm have not received large military orders to ramp up their production capacity to the same levels. Producibility is certainly a valid concern. It must be part of any fair and reasonable competition. It can also be abused to become a back door method of ratifying existing decisions, while adopting the veneer of competition. Which will it be in this case? Only time will tell.
July 11/08: Demonstration. Military.com reports that about 30 legislative aides signed up to attend a July 11 demonstration at Marine Corps Base Quantico. Congressional and industry sources report that the event feature the standard 5.56mm M4 carbine, plus the FN SCAR Mk17 7.62mm (SCAR MK16 is the 5.56mm version that was tested by the Army), – and a modified “M4-style MURG (Modified Upper Receiver Group)” rifle capable of firing a new 6.8mm special purpose cartridge round, among others. Attendees included FN-USA, HK, LWRC who offers receiver group switchouts like HK’s and adds a 6.8mm version, Barrett (REC-7 6.8mm), and Bushmaster. All reportedly avoided commercial sales pitches, and stuck to facts and demonstrations.
Complaints persist from troops on the front lines regarding the current 5.56mm round/riling combination’s lethality. The ballistic characteristics of calibers around 6.8mm have yet to feature a breakthrough military purchase in the face of 5.56mm standardization, but these calibers are gaining growing recognition for their balance of size (can be used with M16 magazines), light weight, and knock-down power.
Participants reportedly had the opportunity to observe the effects of different caliber rounds in translucent ballistic jelly, which simulates human tissue, and to fire the weapons involved. Sens. James Coburn [R-OK] and Ken Salazar [D-CO] remain very active in this area, but the number of participants suggests that their efforts may be gaining traction in spite the Army.

Late December 2007: Test results. DID obtains some exact results from the Army’s testing. The Army has now done 3 dust tests. In the late 2006/Jan 2007 report “Baseline Reliability and Dust Assessment for the M4, M16, and M249,” the M4 jammed 9,836 times – 1 jam every 6 rounds. In a May 2007 “Extreme Dust Test II”, with no competitors, the M4 had 1 jam every 88 rounds, using heavy lubrication. In the November 2007 “Extreme Dust Test III”, as DID has discussed, the competing rifles were subject to significantly more maintenance and lubrication than elite American forces like Delta used in their weapon selection process, or indeed in HK’s own field testing of its HK416s prior to shipment.
We’ll begin with the Army’s overall results, from its own release:
“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.
The failure of M4 barrels at 6,000 rounds confirms SOCOM objections that date back to the Feb 23/01 report “M4A1 5.56mm Carbine and Related Systems Deficiencies and Solutions,” which ended up concluding that “M4A1 Carbine… does not meet the requirements of SOF.” The barrel replacement also increases the rifle’s life cycle costs when compared with the 10,000 round advertised barrel life, as additional barrels are sold to the Army for $240 each. A longer, heavier M16 barrel, which is a competed production weapon, cost $100 by comparison. While the dust test is indeed an extreme test, the 10,000 round requirement is under “all conditions” – not just ideal conditions.
Dec 18/07: The US Army publishes “M-4 Carbine Has High Soldier Confidence Despite Test.” Not exactly a headline to inspire confidence, as the Army acknowledges that the M4 Carbine finished last among the 4 contenders – but amazingly, asserts that the rifle is just fine and shows no interest in buying even the HK416’s parts swap-out into the existing M4:
“After being exposed to the heavy dusting, 10 of each weapon fired 6,000 rounds apiece. They were fired in 50 120-round cycles. Each was then wiped and re-lubricated at the 600 round mark. After 1,200 rounds were fired from each weapon, they were fully cleaned and re-lubricated… “While the M-4 finished fourth out of four, 98 percent of all the rounds fired from it went off down range as they were supposed to do,” Brig. Gen. [Mark] Brown [commander of Program Executive Office Soldier and the Natick Soldier Systems Center] said. “However, the three other candidates did perform better at about a 99 percent rate or better, which is a mathematically statistically significant difference, but not an operationally statistical difference.”… The Army has put an option on an existing contract for 64,450 M4s, according to the general.”
“A mathematically statistically significant difference, but not an operationally statistical difference.” Statistically, 99% is a 100% improvement over 98%. Operationally, I jam every 68 rounds is almost one jam for every 2 30-round magazines. Whereas one jam in 257 rounds would only happen about once in 8 30-round magazines. Readers are left to contemplate the operational significance of those probabilities in a sustained, serious firefight.
4-Rifle test: M4 finishes dead last
June 29/07: Testing. A document circulated on Capitol Hill asking for testing includes these excerpts:
“The Army has claimed “83% reported confidence that the M4 will not suffer major breakage or failure that necessitates repair before further use” – A soldier should be 100% confident that his weapon will not break the next time he fires it… Since the M16 was introduced in Vietnam the answer has always been “It’s the soldiers’ fault”… The Special Operations Command has the most proficient soldiers in the world, they shoot the most and they operate in the most difficult environments – In 2001 SOCOM was highly critical of the reliability of the M4, and they chose to adopt a new weapon – the SCAR. Our Tier 1 units – like Delta Force, and Seal Team 6 have all abandoned the M4 for other weapons that is [sic] significantly more reliable.”
