This video shows the internals of the H&K HK416. One nifty feature is that the handguard screws were designed so that they could be unscrewed using the bolt lugs. The video is well worth watching.

The civilian HK416 is expected to arrive next year.

[ Many thanks to the reader who emailed me the video. ]

A couple of days ago I blogged about H&K winning the USMC's IAR competition. There has been much confusion regarding the IAR competition since then.

Dan Lamothe, who broke the news, updated his The Marine Times article and added that it now appears that the H&K IAR has not officially won but is the frontrunner ...

With several months of testing ahead, the decision isn’t considered final, but it makes the H&K model the clear front-runner in the competition.

...

The Corps will now put H&K IAR through five months of testing beginning in January and taking place in locations ranging from Panama to the Marine Corps Air Ground Combat Center and Marine Corps Mountain Warfare Training Center in California, Eby said. The Corps has ordered 24 H&K IARs for testing, said Capt. Geraldine Care

Rob Curtis who blogs at GearScout (also part of the Military Times) wrote that the DoD appear to done a downselect, rather than awarding H&K an outright win ...

From what we understand, this is actually a downselect to just one system as opposed to a contract win

Dan send me an email regarding my previous comments on the supposed weight of the H&K IAR, which is almost identical to the standard HK416 carbine. He sent me the spec document which H&K provided him with. It does indeed list the weight as just 7.9 lbs!

Daniel E. Watters wrote that he suspects that the Marine command may have been framing the IAR as a partial M249 replacement but in reality they may have just wanted a piston operated full-auto carbine. By procuring what is sold as a new class of weapon they could sidestep the inter-service politics and bureaucracy ...

The weird thing is that the HK416 IAR is roughly the same weight as the M16A4, if not lighter when the latter is fitted with the M5 ARS. I'm certain that someone in Congress will ultimately ask what the HK416 can do that their issue M16A4 retrofitted with full-auto trigger groups can't.

Like others have mentioned, I can't help but wonder if the USMC didn't game the IAR requirements so that a basic carbine could win instead of a HBAR. The idea would be to gradually increase the number of IAR issued so that they could later justify standardizing on it to replace not just the infantry squad's M249, but their M16A4 and M4 as well. By framing it as a service-specific supplement to their M249, they skirted the need to argue with the other service branches over a set of joint requirements.

As for winning the contract, everyone needs to remember that Colt, FN, and HK were already awarded Indefinite Delivery/Indefinite Quantity contracts for their IAR last year. An IDIQ contract guarantees the awardee that they will have a specific minimum of items ordered, with the possibility of additional orders up to a specific maximum. There is no guarantee that more than the stated minimum will ever be ordered. I've long suspected that contracting officers have been purposefully making multiple awards of IDIQ contracts prior to a final downselect in order to head off potential award protests by the disgruntled losers. It is my understanding that by accepting their IDIQ award, the contractor only has grounds to protest if the guaranteed minimum has not ordered before the end of the contract. They cannot protest that they did not receive additional orders in excess of the guaranteed minimum.

Make of all this information as you will. All I know is that DoD procurement was never designed to be understood by a mere mortal such as myself!

Umarex is manufacturing this .22 LR rifle patterned on the HK416¹ . It features ...

• Metal receivers.
• Functional dust cover.
• Full length picatinny rail.
• Adjustable stock.
• H&K style diopter iron sights. Adjustable for elevation or windage.
• 16" barrel.
• Pistol grip with compartment (for spare batteries, tools, etc.)

The rifle will be sold with either a 10 or 20 round magazine but 30 round mags will be available for purchase.

The previous Umarex .22 rifle, the Colt M4, had some serious problems. Justin Biddle, Umarex's Marketing Manager, assured me that they have been made changes to the Umarex action and sorted out the issues experienced by the M4 owners.

Hat Tip: On Point Supply

After a year of speculation and commentary from pundits, myself included, the Marine Times reports that the H&K has won the competition and that their entry will enter production next year ...

The Marine Corps has selected the infantry automatic rifle made by Heckler & Koch as the weapon that will replace the M249 Squad Automatic Weapon in infantry fire teams, a senior service official told Marine Corps Times on Wednesday.

The H&K IAR “was truly the best in the class on multiple levels and will finally allow the billet of automatic rifleman to be performed as intended without the disruption of the squad integrity that the M249 created,” Chief Warrant Officer 5 Jeffrey Eby, the Corps’ senior gunner, said in an e-mail.

Despite what is said in the above quotation, I do not think that the SAW is being replaced outright. The Marine Times has at times reported that the SAW would be replaced with the IAR, and at other times reported that it would augment the IAR, not replace it ...

The plan is to buy 4,100 IARs and reduce the number of SAWs in the Corps from 10,000 to 8,000, Cantwell said.

“We are still going to maintain SAWs in the company,” he said. “Only 2,000 SAWs will be replaced. The reminder will be kept as an organizational weapon for when commanders need them.”

The H&K entry was a modified version of their HK416 piston-operated AR-15 rifle. Unlike the Colt and FN entries, it is said to fire only from a closed bolt. Given the lack of an open-bolt fire mode I had presumed it was the least likely choice for an automatic rifle.

Presumably it is fitted with a heavy barrel, like H&K's previous, and commercially unsuccessful, attempt at the automatic rifle: the MG36. The Marine Corps has been reporting the weight of the 16.5" barreled H&K IAR as being 7.9 lbs. This is not possible as a standard 16.5" barreled Hk416 weights in at 7.84 lbs. I also think that the photo of the H&K IAR shown by the Military Times is that of a standard HK416.

I have contacted H&K to see if they are willing to publicly acknowledge if they have won. If they do, I will endeavor to get the specs of the new weapon.

UPDATE: The Marines Times has an updated article here.

Many thanks to Mark and Matt for sending me the news.

Another new gun on display at DSEi was this H&K HK416 sub-carbine / PDW. What is very interesting about this gun is the buttstock and upper receiver design.

New H&K Sub-Carbine

It has a much shortened buffer tube and a collapsible stock in the H&K G3 / MP5 style.

A regular HK416 carbine

This firearm appears to be positioned in direct competition to the Sub-Compact Weapon (SCW) that Colt is developing. The SCW features a similarly shortened buffer tube.

I think the H&K design is much more elegant. The H&K stock pull straight out, while the Colt stock must be unfolded out and then down before it can be adjusted for length.

A close-up of the H&K Stock.

Now if H&K would just stop hating us and start selling this nifty upper to us civilians!

Big thank you to Lusaka for the information and photo.

UPDATE:

REMOV has kindly provided me with these photos that he took of the new H&K. The gun has a 9.3" barrel.

Many thanks REMOV!

UPDATE: The Tactical Wire got it wrong. Production was not halted.
Tactical Wire claims that significant problems with the HK416 have been uncovered and production has been halted:

The Tactical Wire has learned from very reliable sources that the US military has encountered significant problems with H&K Model 416s in combat conditions. HK has suspended production pending an internal investigation and inspection of that weapon system.

Very interesting if true. I previously reported that Norwegian soldiers were having problems with their HK416s.

Thanks to Ed Friedman for alerting me to this.

UPDATE: In response to jdun1911: I don’t think this is an Aprils fools joke:

In my recent article about the Norwegian H416 rifle, Mauken, a Norwegian soldier, posted a link to this article at aftenposten.no (I have translated it into english using google):

Soldiers may have been sick of the military’s new rifle

Army turns the alarm after a number of officers and soldiers have health problems after the shooting with the military’s new standard rifle, “HK 416″.

Gun are heirs to AG3, and is about to be phased in for all Armed Forces branches. Some departments, including the Norwegian soldiers in Afghanistan, has had the gun in about a year, writes Dagbladet.no.

Hærstaben have been in three different concern from messages incidents where about 40 skyttere have experienced various health problems. It has been reported that strong discomfort in the chest, neck and munnhule after the shooting, unpleasant cough for several hours after the shooting, nausea, fever, headache, joint and cold svetting after the shooting.

Chief of Staff in hærstaben, Brigadier Rune Jakobsen, have now initiated full investigation to find out what it evokes the most serious problems. It has already been initiated medical examinations of the involved personnel.

One of the main theories in the military is now working on the basis that it is the gunpowder gas from the ammo, and not the weapon, which causes problems. HK 416 uses a smaller caliber, and thus a different type than the old munitions AG3.

Norway has been using the H&K G3 which is chambered in 7.62×51mm NATO. The HK416 that is being adopted is an AR-15 derivative and chambered in 5.56×45mm NATO.

It is not uncommon for an ammunition producing country to develop a new powder specifically optimized for the a new cartridge / rifle combination when it is adopted by the nations’ armed forces. It is possible that this powder used in the Norwegian 5.56mm ammunition is toxic. Maybe the lubricant they are using reacts badly with the gas from the powder? Maybe plastic parts are melting and releasing a toxic vapor? It will be interesting to see how this story develops.

Thanks to Mauken for the link.

Tanfo, a Norwegian soldier, reports at the ar15.com forum that they have been having problems with their new HK416 rifles.

Norwegian configured HK416 with suppressor.

One of the problems is that the piston system locks up if the gun is taken outdoors from a warm building when the humidity in the air freezes in the Norwegian arctic conditions. The C8 (Colt Canada full-auto AR-15) that is used by the Norwegian special forces also has this problem but can be fixed in a much more timely manner than the HK416.

Apparently the gas regulator, which that controls the amount of gas flowing into the gas piston system, often switches modes during firing. The gun will not function properly if set to the suppressor mode if a suppressor is not being used.

HK416 Gas regulator

I imagine the Norwegian will have these problems sorted out in the next few years. It does seem odd that they did not identify the problems before purchasing the rifles.

Many thanks to Jay for the link.

H&K fans rejoice. The HK416 / HK417 piston driven AR-15 derivatives are finally coming in a semi-automatic form for civilians. The civilian 5.56×45mm HK416 is called the MR556 and the 7.62×51mm HK417 civilian equivalent is the MR762. They are expected to arrive in late 2009.

5.56×45mm MR 556

From HK:

A direct descendent of the HK416, the MR556 is a semi-automatic rifle developed by Heckler & Koch as a premium level commercial/civilian firearm. Like the HK416, the MR556 is a major product improvement of conventional AR-type carbines and rifles.

Using the HK-proprietary gas piston system found on the HK416 and G36, the MR556 does not introduce propellant gases and carbon fouling back into the rifle’s interior, making it the most reliable of any AR-type firearm.

The MR556 will be produced at Heckler & Koch’s new manufacturing facility at Newington, New Hampshire from American and German made components. To conform to German export regulations, certain design changes made in the MR556 prevents the rifle’s upper receiver from being used on other AR-style firearms.

So in other words this is not an AR-15 and in theory would not be banned as a named rifle on AWB 2.0.

Specs for the MR 556

Caliber: 5.56 x 45 mm NATO
Length, maximum (stock extended): 37.68″
Length, minimum (stock retracted): 33.90″
Overall width: 3.07″
Height: 9.45″
Barrel Length : 16.5″
weight (without magazine): 8.60 lb
Trigger pull : 7.64 lb
Barrel Profile: 6 lands & grooves, right twist, 1 in 7 in
Sight radius : 14.60″

Oddly enough both models are being shipping with 10 round magazines … AWB 2.0 fears?

7.62×51mm MR 762

Specs for the MR 762
Length, maximum (stock extended) : 39.10″
Length, minimum (stock retracted) : 35.94″
Overall width: 3.23″
Height : 8.36″
Barrel Length: 16.6″
Weight (without magazine): 9.60 lb
Trigger pull: 7.64 lb
Barrel Profile: 6 lands & grooves, right twist, 1 in 12 in
Sight radius: 16.14″

I will update this page as more information becomes available.

Earlier this year the Turkish Ministry of Defense announced they will be switching from the G3 7.62mm rifle to the HK416. The Turkish government owned arms and ordnance manufacturer MKEK will be producing the rifle under license from Heckler & Koch.

The H&K G3 battle rifle has been phased out in many countries and replaced with assault rifles chambered in intermediate cartridges. Along with the H&K G3, MKEK also produces the a variety of H&K MP5 models so the move to another H&K rifle is not surprising. Norway is also replacing the G3 with the HK416.

The pistol grip and stock look different to most of the HK416 photos on the internet. The wikipedia page has a photo with “HK416N” markings and the same configuration. The photo is marked for deletion from Wikipedia and there are few other references to the “HK416N” on google.

Mehmetçik-1 markings

I cannot see any other differences between the Mehmetçik-1 and the HK416N other than the MKEK markings. The only different I have read about on a couple of forums is that MKEK are using different manufacturing techniques and different metals than H&K, which I take to mean a slightly different aluminum and steel alloys, which is not surprising.

The scope pictured above is the Elcan SpecterOS34x scope which well known for its use on the Canadian Diemaco C7/C8. The grenade launcher is the H&K AG416.

The Turkish Wikipedia page says the rifle will be manufactured in four different models. A Sub-carbine (10.5″ barrel), Carbine (14.5″ barrel), Rifle (16.5″ barrel) and “Distance” (Sniper/Marksmen, 20″ barrel).

Below is a video of a press conference with that important Turkish guy showing off the weapons and looking out of his depth:

By all accounts the HK416 is a great rifle combining the best of the AR-15 platform with the benefits of a gas piston system.

Turkey has also adopted a new sniper rifle that I cannot identify. Anyone know what it is? See the below photo.

UPDATE: Alcibiades, correctly identified it as the 7.62×51mm JNG 90, also made by MKEK.

Hat Tip: GunPundit

This animation shows how both the 416 and M4 operate and explains the differences between the M4/M16/AR15 direct-gas impingement system and the H&K 416 piston system.

View the animation here. Below is a screenshot.

The ArmyTimes has written about how the army is stuck with the M16/M4 while spec ops are moving to the H&K 416:

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.
