The '''Heckler & Koch HK416''' is an [[Engineering:Assault rifle|assault rifle]] chambered for the [[Engineering:5.56×45mm NATO|5.56×45mm NATO]] [[Engineering:Cartridge (firearms)|cartridge]]. It is designed and manufactured by the German company Heckler & Koch.

Although the design is based on the AR-15 class of firearm (specifically the Colt [[Engineering:M4 carbine|M4 carbine]] family issued to the U.S. military), it uses a proprietary [[Engineering:Gas-operated reloading|short-stroke gas piston system]] from Heckler & Koch's earlier G36 family of rifles.

The HK416 is the standard assault rifle of the Norwegian Armed Forces and the United States Marine Corps (named M27), and it has been selected by the French Armed Forces to replace the FAMAS. Other users of the HK416 include the German Army and the Irish Army Ranger Wing, as well as the US Navy's SEAL Team Six, who used it to kill Osama bin Laden in 2011.<ref>{{cite web |url=http://www.popularmechanics.com/military/weapons/g536/face-time-with-the-hk416-the-gun-that-killed-bin-laden/? |title=Face Time With the Gun That Killed Bin Laden |date=7 June 2011 |website=Popular Mechanics |access-date=14 May 2017 |archive-url=https://web.archive.org/web/20170508032802/http://www.popularmechanics.com/military/weapons/g536/face-time-with-the-hk416-the-gun-that-killed-bin-laden/ |archive-date=8 May 2017 |url-status=live}}</ref><ref>{{cite web |last1=Bedard |first1=Paul |title=The Gun That Killed Osama bin Laden Revealed |url=https://www.usnews.com/news/washington-whispers/articles/2011/05/11/the-gun-that-killed-osama-bin-laden-revealed |website=US News |access-date=11 November 2018 |date=11 May 2011 |archive-url=https://web.archive.org/web/20110626012337/http://www.usnews.com/news/washington-whispers/articles/2011/05/11/the-gun-that-killed-osama-bin-laden-revealed |archive-date=26 June 2011 |url-status=live}}</ref>

== History ==
The United States Army's Delta Force, at the request of R&D NCO Larry Vickers, collaborated with Heckler & Koch to develop a new carbine in the 1990s for use in [[Social:Close quarters combat|close quarters combat]]. At this point, they were equipped with the Heckler & Koch MP5, whose 9&nbsp;mm bullet was considered too weak, and the M4 carbine, which was considered too large.<ref>{{Cite episode |series=Larry Vickers Podcast |title=Ep. 3: HK416 Presented by Firearms Trainers Association |url=https://www.youtube.com/watch?v=SOvPG2jfsRE |archive-url=https://ghostarchive.org/varchive/youtube/20211221/SOvPG2jfsRE |archive-date=2021-12-21 |url-status=live |via=YouTube}}{{cbignore}}</ref> During development, Heckler & Koch capitalized on experience gained developing the ''Bundeswehr''{{'}}s Heckler & Koch G36 assault rifle, the U.S. Army's XM8 rifle project (cancelled in 2005) and the British Armed Forces SA80 A2 upgrade programme. The project was originally called the '''Heckler & Koch M4''', but this was changed in response to a trademark infringement suit filed by Colt Defense.<ref>As mentioned in {{Cite court |litigants=Colt Defense LLC v.

Delta Force replaced its M4s with the HK416D in March 2005, after tests revealed that the piston operating system significantly reduces malfunctions while increasing the life of parts.<ref name=armytimes>{{cite news |url=http://www.armytimes.com/news/2007/12/army_carbine_dusttest_071217/ |title=Newer carbines outperform M4 in dust test |first=Matthew |last=Cox |work=Army Times |archive-url=https://archive.today/20120630044756/http://www.armytimes.com/prime/2007/12/army_carbine_dusttest_071217/ |archive-date=30 June 2012 |url-status=dead |access-date=2013-10-18}}</ref> The HK416 has been tested by the United States military and is in use with some law enforcement agencies. It has been adopted as the standard rifle of the Norwegian Armed Forces (2008) and the French Armed Forces (2017) and is used by many special operations units worldwide.

A modified variant underwent testing by the United States Marine Corps as the M27 Infantry Automatic Rifle (IAR). After the Marine Corps Operational Test & Evaluation Activity supervised a round of testing at MCAGCC Twentynine Palms, Fort McCoy, and Camp Shelby (for dust, cold-weather, and hot-weather conditions, respectively). As of March 2012, fielding of 452 IARs had been completed of 4,748 ordered. Five infantry battalions: 1st Light Armored Reconnaissance Battalion and 2nd Battalion, 4th Marines, out of Camp Pendleton; 1st Battalion, 3rd Marines, out of Marine Corps Base Hawaii; 1st Battalion, 9th Marines, out of Camp Lejeune; and 1st Battalion, 25th Marines, out of Fort Devens, have deployed the weapon.<ref name="testing">{{cite news |url=http://www.marinecorpstimes.com/news/2010/08/marine_iar_080810w/ |title=SAW replacement set for real world testing |last=Lamothe |first=Dan |date=9 August 2010|work=Marine Corps Times |access-date=10 August 2010 |url-status=dead |archive-url=https://web.archive.org/web/20120308033204/http://www.marinecorpstimes.com/news/2010/08/marine_iar_080810w/ |archive-date=8 March 2012}}</ref><ref name="ramping">{{cite news |url=http://www.marinecorpstimes.com/news/2012/03/marine-corps-ramps-up-fielding-new-auto-rifle-031112w/ |title=Corps ramps up fielding of new auto rifle |last=Lamothe |first=Dan |date=11 March 2012 |work=Marine Corps Times |access-date=25 March 2012 |archive-url=https://web.archive.org/web/20120323024736/http://www.marinecorpstimes.com/news/2012/03/marine-corps-ramps-up-fielding-new-auto-rifle-031112w |archive-date=23 March 2012 |url-status=dead|df=dmy-all}}</ref> In December 2017, the Marine Corps revealed a decision to equip every Marine in an infantry squad with the M27.<ref>{{cite news |url=https://www.military.com/kitup/2018/01/05/m27s-and-head-toe-gear-overhaul-way-marine-grunts.html |title=M27s and 'Head-to-Toe' Gear Overhaul on the Way for Marine Grunts |first=Hope Hodge |last=Seck |date=5 January 2018 |website=Military.com |url-status=live |archive-url=https://web.archive.org/web/20180107233105/https://www.military.com/kitup/2018/01/05/m27s-and-head-toe-gear-overhaul-way-marine-grunts.html |archive-date=2018-01-07}}</ref>

== Design ==
The HK416 uses a proprietary short-stroke gas piston system that derives from the HK G36.<ref>{{cite patent |country=US |number=2951424 |invent1=Stoner, Eugene M. |assign1=Fairchild Engine and Airplane Corp |status=Patent |title=Gas operated bolt and carrier system |pubdate=1960-09-06 |gdate=1960-09-06 |pridate=1956-08-14 |fdate=1956-08-14<!-- |url=https://www.google.com/patents/US2951424 |website=Google Patents |publisher=USPTO |access-date=2016-09-08 |archive-url=https://web.archive.org/web/20160724162338/http://www.google.com/patents/US2951424 |archive-date=2016-07-24 |url-status=live-->}}</ref><ref name="Heckler-Koch.de – HK416">{{cite web |url=http://www.heckler-koch.de/HKWebText/detailProd/1928/337/4/19 |title=HK416 |website=Heckler & Koch |access-date=2010-02-12 |archive-url=https://web.archive.org/web/20110717191144/http://www.heckler-koch.de/HKWebText/detailProd/1928/337/4/19 |archive-date=2011-07-17 |url-status=dead}}</ref> The HK system uses a short-stroke piston driving an operating rod to force the bolt carrier to the rear. This design prevents combustion gases from entering the weapon's interior—a shortcoming with direct impingement systems.<ref>{{cite web |url=http://www.militarytimes.com/projects/flash/2007_02_20_carbine/ |title=Carbine |website=Military Times |url-status=dead |archive-url=https://web.archive.org/web/20091228092153/http://www.militarytimes.com/projects/flash/2007_02_20_carbine/ |archive-date=28 December 2009}}</ref> The reduction in heat and fouling of the bolt carrier group increases the reliability of the weapon and extends the interval between stoppages. During factory tests the HK416 fired 10,000 rounds in full-auto without malfunctioning. The HK416's piston system was originally self-regulating in theory, but in the default position tends to give increased recoil over an adjustable gas system. A user adjustable gas regulator was added in later variants.<ref name="nationalinterest.org">{{cite web |title=Meet the Sig Sauer 516 Rifle: The Best AR-15 Around? |url=https://nationalinterest.org/blog/buzz/meet-sig-sauer-516-rifle-best-ar-15-around-64661 |first=Charlie |last=Gao |website=[[Social:The National Interest|The National Interest]] |date=2019-06-30 |access-date=2020-10-11}}</ref>

The HK416 is equipped with a proprietary accessory rail forearm with MIL-STD-1913 rails on all four sides. This lets most current accessories for M4/M16-type weapons fit the HK416. The HK416 rail forearm can be installed and removed without tools by using the bolt locking lug as the screwdriver. The rail forearm is "free-floating" and does not contact the barrel, improving accuracy.

The HK416 has an adjustable multi-position telescopic butt stock, offering six different lengths of pull. The shoulder pad can be either convex or concave and the stock features a storage space for maintenance accessories, spare electrical batteries or other small kit items. It can also be switched out for other variations like Magpul stocks.

The trigger pull is {{convert|34|N|lb-f|1|lk=on|abbr=on}}. The empty weight of a HK416 [[Engineering:Magazine (firearms)|box magazine]] is {{convert|250|g|abbr=on}}.

The HK416's barrel is [[Engineering:Forging|cold hammer-forged]] with a 20,000-round service life and features a 6-groove {{cvt|178|mm|in}} right hand [[Engineering:Rifling|twist]]. The cold hammer-forging process provides a stronger barrel for greater safety in case of an obstructed bore or for extended firing sessions. Modifications for an over-the-beach (OTB) capability such as drainage holes in the bolt carrier and buffer system are available to let the HK416 fire safely as quickly as possible after being submerged in liquids like water.<ref>{{cite patent

== Adoption ==
In July 2007, the U.S. Army announced a limited competition between the M4 carbine, [[Engineering:FN SCAR|FN SCAR]], HK416, and the previously shelved HK XM8. Ten examples of each of the four competitors were involved. Each weapon fired 60,000 rounds in an extreme dust environment. The shoot-off was for assessing future needs, not to select a replacement for the M4.<ref>{{cite news |first=Christian |last=Lowe |website=Military.com |date=2007-06-27 |url=http://www.military.com/NewsContent/0,13319,143790,00.html?ESRC=army-a.nl |title=Army Agrees to M4 Sand Test Shoot-Off |access-date=2007-09-22 |archive-url=https://web.archive.org/web/20071012153212/http://www.military.com/NewsContent/0,13319,143790,00.html?ESRC=army-a.nl |archive-date=2007-10-12 |url-status=dead}}</ref><ref>{{cite web |url=http://www.armytimes.com/news/2007/07/army_rifle_070715/ |title=M4 to face new rifles in dust-chamber test |first=Matthew |last=Cox |date=July 20, 2007 |website=Army Times |archive-url=https://archive.today/20120729100432/http://www.armytimes.com/news/2007/07/army_rifle_070715/ |archive-date=29 July 2012 |url-status=dead |access-date=2007-09-22}}</ref> The XM8 scored the best, with only 127 stoppages in 60,000 total rounds, the FN SCAR Light had 226 stoppages, while the HK416 had 233 stoppages.

==== M27 IAR ====
The M27 Infantry Automatic Rifle is a squad automatic weapon variant developed from the D16.5RS, adopted in 2011 by the United States Marine Corps. In 2018 the USMC decided to adopt the M27 IAR as their infantry standard service rifle.

=== HK416 A5 ===
The '''HK416 A5''' is an improved variant that was first seen in the Individual Carbine competition.<ref name="HK416A5">{{cite web |url=http://www.thefirearmblog.com/blog/2012/10/17/the-new-heckler-koch-hk416a5/ |title=The New Heckler & Koch HK416A5 |last=Johnson |first=Steve |date=2012-10-17 |website=The Firearm Blog |access-date=2013-10-18 |url-status=live |archive-url=https://web.archive.org/web/20131023053138/http://www.thefirearmblog.com/blog/2012/10/17/the-new-heckler-koch-hk416a5/ |archive-date=23 October 2013}}</ref> It features a stock similar to that of the G28 designated marksman rifle, except slimmer and non-adjustable. The rifle features an improved tool-less adjustable gas regulator for suppressor use, which can accommodate barrel lengths down to {{convert|267|mm|abbr=on|1}} without modifications. It also features a redesigned lower receiver with ambidextrous fire controls, optimised magazine and ammunition compatibility, a repair kit housed inside the pistol grip, and a Flat Dark Earth colour scheme.<ref name="HK416A5" /> The stock has a fixed buttplate and no longer has a storage space, as well as the sling loops removed from it. The V2 HK Battle grip is incorporated, which has the V2 grip profile with the storage compartment of the V1 grip for tools. The handguard uses a new hexagonal-shaped cross bolt that cannot be removed by the bolt locking lugs but instead by the takedown tool housed inside the grip.<ref>{{cite web |date=2012-10-17 |title=HK416A5 – newest evolution of famous assault rifle |url=http://montrala.blogspot.com/2012/10/hk416a5-newes-evolution-of-famous.html |url-status=live |archive-url=https://web.archive.org/web/20131024124520/http://montrala.blogspot.com/2012/10/hk416a5-newes-evolution-of-famous.html |archive-date=2013-10-24 |access-date=2013-10-18 |website=Montrala}}</ref> It has a "heavy duty castle nut", which is more robust than the previous version, therefore making that weak spot more resistant to impact.

As of 2013, Heckler & Koch replaced the original HK416 with the A5 variant.
*HK416 A5 – 11": sub-compact with a 279&nbsp;mm (11.0&nbsp;in) barrel
*HK416 A5 – 14.5": carbine 368&nbsp;mm (14.5&nbsp;in) barrel

*HK416 A5 – 20": full-sized rifle 508&nbsp;mm (20&nbsp;in) barrel

==== G38 ====
In 2014, The HK416 A5 has been type classified by the German federal government as the '''G38''', according to Strategie-Technik.<ref>{{Cite web |date=2014-09-01 |title=The HK416A5 Is Now The G38 - |url=https://www.thefirearmblog.com/blog/2014/09/01/hk416a5-now-g38/ |access-date=2023-04-13 |website=The Firearm Blog |language=en-US}}</ref> Heckler & Koch offers the G38 in two barrel lengths, an 11- and 14.5-inch barrel.<ref>{{Cite web |title=Heckler-Koch |url=https://www.heckler-koch.com/en/Products/Military%20and%20Law%20Enforcement/Assault%20rifles/HK416 |access-date=2023-04-13 |website=Heckler-Koch |language=en}}</ref>

==== G95 ====
[[File:IEA Mil Optics GmbH HK G95 m Eotech EXPS und G33.jpg|thumb|A close-up image of a G95's fire selector with EOTech EXPS3-0 holographic weapon sight and G33 magnifier on the receiver rail.]]
The G95 is designed for the German KSK and KSM special forces unit. During field testing of the rifle it was known as the ''HK416 A7''.<ref name=":1" /> It is similar to the HK416 A5 variant but with a 45-degree safety selector, that rotates 45 degrees rather than 90 degrees as on the A5 variant safety selector. The new configuration of the selector is comparable to those of aftermarket 45-degree safety selectors. The G95 also features a HKeyMod rail system, which is more lightweight than the traditional [[Engineering:Picatinny rail|Picatinny rail]] systems. The HKeyMod rail system is also compatible with the HK416 A5 variant.<ref>{{cite web |url=http://www.thefirearmblog.com/blog/2017/10/18/new-photos-new-hk416a7/ |title=New Photos of The New HK416A7 |first=Matthew |last=Moss |date=18 October 2017 |website=The Firearm Blog |access-date=12 April 2018 |archive-url=https://web.archive.org/web/20180412212025/http://www.thefirearmblog.com/blog/2017/10/18/new-photos-new-hk416a7/ |archive-date=12 April 2018 |url-status=live}}</ref>

==== G95A1 ====
In March 2021, the German Federal Ministry of Defence announced the adoption of the ''G95A1'' to supersede the G36 as the standard rifle of the German Armed Forces.<ref>{{Cite web |date=2022-06-22 |title=HK416 A8: Bundeswehr darf Beschaffung eines neuen Sturmgewehrs von Heckler & Koch fortführen |url=https://soldat-und-technik.de/2022/06/bewaffnung/31923/hk416-a8-sturmgewehr-bundeswehr/ |access-date=2022-10-31 |website=soldat-und-technik.de |language=de-DE}}</ref> G95A1 is similar to the G95, but it features a height-adjustable shoulder support on the stock, a steeper grip angle as well as a shorter hand guard to comply with the required maximum weight of {{convert|3.5|kg|abbr=on|2}} according to the tender.<ref>{{Cite web |last1=Lt.Dan |last2=Lt.Dan |date=2021-03-02 |title=Bundeswehr: Germany's Next Topmodel |url=https://www.spartanat.com/2021/03/bundeswehr-germanys-next-topmodel/ |access-date=2022-10-31 |website=SPARTANAT |language=de-DE}}</ref> During field testings the rifle was known as the ''HK416 A8''. According to the Federal Procurement Office (BAAINBw Federal Office for Equipment, Information Technology and Use of the ''Bundeswehr'') the ''Bundeswehr'' will receive the weapon designated as '''G95A1''' as the new standard rifle. The ''Kurz'' or short barrelled version for "specialized forces" will be designated as '''G95KA1'''.<ref name="soldat-und-technik.de">{{cite web |title=Bundeswehr beauftrag Heckler & Koch mit der Lieferung des neuen "System Sturmgewehr" |url=https://soldat-und-technik.de/2023/01/bewaffnung/33814/bundeswehr-beauftrag-heckler-koch-mit-der-lieferung-des-neuen-system-sturmgewehr/ |website=soldat-und-technik.de |access-date=23 January 2023 |language=German |date=23 January 2022}}</ref>

=== Civilian variants ===
Civilian variants of the HK416 and HK417 introduced in 2007 were known as MR223 and MR308 (as they remain known in Europe). Both are semi-automatic rifles with several sporterized features. At the 2009 SHOT Show, these two firearms were introduced to the U.S. civilian market renamed respectively MR556 and MR762.<ref>{{cite web |url=http://www.tactical-life.com/online/products/heckler-kochs-mr556-mr762-rifles/ |title=Heckler & Koch's MR556 & MR762 Rifles |access-date=2011-06-22 |website=Tactical Life |date=2009-01-20 |archive-url=https://web.archive.org/web/20110817070001/http://www.tactical-life.com/online/products/heckler-kochs-mr556-mr762-rifles/ |archive-date=2011-08-17 |url-status=live}}</ref> There is another variant of the MR556 called the MR556A1, which is an improved version of the former.<ref>{{cite web |url=http://www.tactical-life.com/online/guns-and-weapons/heckler-koch-mr556a1/ |title=Heckler & Koch MR556A1 |first=Jorge |last=Amselle |access-date=2011-06-22 |website=Tactical Life |archive-url=https://web.archive.org/web/20110526175335/http://www.tactical-life.com/online/guns-and-weapons/heckler-koch-mr556a1/ |archive-date=2011-05-26 |url-status=live}}</ref> It was created with input from American special forces units.<ref>{{cite web |url=http://www.tactical-life.com/online/exclusives/sneak-peek-hk%E2%80%99s-mr556a1/ |title=Sneak Peek: HK's MR556A1 |access-date=2011-06-22 |first=Jorge |last=Amselle |website=Tactical Life |date=2011-01-10 |archive-url=https://web.archive.org/web/20110828215100/http://www.tactical-life.com/online/exclusives/sneak-peek-hk%E2%80%99s-mr556a1/ |archive-date=2011-08-28 |url-status=live}}</ref> The MR556A1 lets the upper receiver attach to any M16/M4/AR-15 family lower receiver, as the receiver take-down pins are in the same standard location. The original concept for the MR556 did not allow for this, as the take-down pins were located in a "non-standard" location. The MR223 maintains the "non-standard" location of the pins, disallowing attachment of the upper receiver to the lower receivers of any other M16/M4/AR-15 family of rifles.

As of 2012, the MR556A1 upper receiver group fits standard AR-15 lower receivers without modification, and functions reliably with standard STANAG magazines. HK-USA sells a variant under the MR556A1 Competition Model nomenclature; it comes with a 14.5" free-float Modular Rail System (MRS), 16.5" barrel, OSS compensator and Magpul CTR buttstock. The firearm's precision is specified as 1 MOA by Heckler & Koch. In Europe, the MR223A3 variant is sold with the same cosmetic and ergonomic improvements of the HK416A5. The French importer of Heckler & Koch in France, RUAG Defence, have announced that they are going to sell two civilian versions of the HK416F, named the MR223 F-S (14.5" Standard version) and MR223 F-C (11" Short version).<ref>{{cite web |url=http://www.gunsandweapons.net/heckler-koch-hk416/ |title=Heckler & Koch HK416 |access-date=2013-03-22 |website=Guns and Weapons |archive-url=https://web.archive.org/web/20130530130619/http://www.gunsandweapons.net/heckler-koch-hk416/ |archive-date=2013-05-30 |url-status=dead}}</ref>
