Heckler & Koch HK416

The Heckler & Koch HK416 is the best handgun out there today. It’s gas-operated, chambered for the 5.56×45 NATO cartridge, and has all of the features and functionality of an AR-15 rifle. It’s one of the best handguns out there today.

It was developed by the Heckler & Koch’s G36 family of rifles. The HK416 is the standard assault rifle of the Norwegian armed forces, and it’s also selected by the French armed forces to replace the FAMAS.

The HK416 was used by the German Army, the Irish Army, and the US Navy. They’re also currently being used by the US Army Rangers and the United States Navy Seal Team Six.

Heckler & Koch HK416 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 close quarters combat.

At this point, they were equipped with the Heckler & Koch MP5, whose 9mm bullet was considered too weak, and the M4 Carbine, which was considered too large. During development, Heckler & Koch capitalised on experience gained developing the Bundeswehr’s Heckler & Koch G36 assault rifle, the U.S.

The XM8 project was originally called the Heckler & Koch M4, and then renamed to the M4A1 (see above). The British Armed Forces replaced their M4s with the SA80A2 (see above) in 2004 after tests revealed that the piston operating system significantly reduced malfunctions and increased the life of parts. Delta Force is currently in use with some law enforcement agencies.

It has been adopted as the standard rifle of the Norwegian Armed Forces and it’s used by many special operations units worldwide. The modified version of the rifle underwent testing by the United States Marine Corps as the M27 Infantry Automatic Rifle.

A field test was conducted by the Marine Corps Operational Test & Evaluation Activity (MCOTEA) at MCAGCC Twentynine Palms, Fort McCoy, and Camp Shelby for dust, cold weather, and hot weather.

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 deployed the weapon.


Design. The HK416 uses a HK-proprietary short-stroke gas piston system that derives from the HK G36, forgoing the direct gas-impingement system action that is standard in AR-15 rifles.

These modifications to the weapons allow it to function while it is being fired. The reduction in heat and fouling of the bolt carrier group increases the reliability of the weapon and extends the interval between stoppages.

The HK416 has been through rigorous testing in the hands of several different organizations. It was tested in a live fire role by several different groups. When the HK416 fires, the rifle’s gas system is designed to be self regulating. It will not allow the user to over-run the rifle.

A user adjustable gas regulator was added in later variants. It’s equipped with a proprietary accessory rail forearm that let most current accessories for M4/M16-type weapons fit it.

The HK416 is available in several different lengths, and its adjustable multi-position telescopic butt stock offers six different lengths of pull.

The magazine is built with a flat top so it’s easier to load and an external clip system allows you to carry your weapon with ease. It has a storage area for a spare magazine and it’s reversible to fit most weapon styles.

1.The gun itself weighs 6lbs (3.5kg), but it doesn’t hold the magazine. It’s full auto capable and has a trigger pull of 4.2lb and is designed to handle up to 20,000 rounds of fire without damage. It’s manufactured by Heckler & Koch, who’s responsible for the US Army’s M16/M4 series of weapons.

The cold hammer-forging process provides a stronger barrel for greater safety in case of an obstructed bore or for extended firing sessions. A modified over-the-beach capability is available so the HK416 will be able to fire safely even if it gets wet. The bolt is equipped with a safety feature that prevents the firing pin from coming into contact with the cartridge’s primer.

This HK416-type upper will only work with the full-height AR-15 hammer. It’s a factory-only feature, not available through aftermarket parts sources.


The adoption of the M4 is the first in a long list of things that will be happening in the next decade in the defense industry, as well as some surprising ones like a limited competition between the M4, FN SCAR, HK416, and the previously shelved HK XM8.

Each weapon fired only 2,200 rounds. The shoot-off was between three carbines, not to pick a new one for the Marine Corps. The XM8 had the lowest number of stoppages, with only 124 of 2,200 total rounds, the FN SCAR Light had 156 of 2,200 rounds, and the HK416 had 165 of 2,200 rounds.

With the new magazines, the M4 could be combat ready by Spring of 2008. The Army said that it was planning to have magazines ready by the end of next year and the Marine Corps could have them in production within a few months after the testing.

The HK416 is the military variant of the HK417, an assault rifle and the standard-issue sidearm of the Hong Kong Police Force. The HK416 was selected as the primary weapon of the HKU24 and the HKU31 and HKU51 submachine guns. The HK416 became the standard issue sidearm for all ranks of the Royal Canadian Mounted Police in 2005.

The Canadian government issued an open tender to replace the C7A2 carbine with the HK416, but only the Smith & Wesson Model 640 was considered. In 2015, the US government approved the purchase of 12,000 HK416s for use by its national guard forces. In 2017, the HK417 was selected to be the replacement for the M16A1 in service with the U.S. Marine Corps.

In July 2010, the HK416 IAR was designated as the M27 and 450 were procured for additional testing. The Turkish company Makina ve Kimya Endustrisi Kurumu (“Mechanical and Chemical Industry Corporation”) has considered manufacturing a copy of the HK416 as the MKEK Mehmetçik-1 for the Turkish Armed Forces.

Army officials during an invitation-only Industry Day on 13 November 2008. The goal of the Industry Day was to review current carbine technology prior to writing formal requirements for a future replacement for the M4 carbine. They were given the opportunity to see the newest developments in HK416 design and manufacture.

The winner of the individual carbine competition was a weapon called the HK416A5. It was an effective weapon, but the problem was that it was never tested by firing rounds.


The HK416 chambered for 56×45mm NATO is offered in multiple barrel lengths, and is also offered to the law enforcement market only, as the D10RS, D5RS, and D20RS. It has become the standard issue rifle for the U.S. military and is used by many police forces around the world.

In 2012 it beat a competition to become the US Army’s next generation assault rifle. It features a shorter barrel, a longer stock and adjustable sights. The US Army issued an updated solicitation for the M27 Infantry Automatic Rifle in late 2013.

In 2018, the USMC decided to adopt the M27 IAR as their standard service rifle.

HK416 A5

The HK416 A5 has been modified for the Individual Carbine event.

The improved adjustable gas regulator tool-less design offers the same reliable function of the previous model. The redesigned lower receiver includes optimized magazine and ammunition compatibility and a repair kit within the pistol grip.

The V2 HK Battle Grip is the best handguard for the V2 HK. It is designed to use the same hexagonal cross bolt as the V1 grip, with the added storage compartment of the V1 grip. The handguard uses a new hexagonal-shaped cross bolt that can only be removed by the takedown tool housed inside the grip. This handguard is more durable than the previous version, thus making the weak spot (the hole for the hexagonal bolt) more resistant to impact.

The Heckler & Koch HK416 is one of the most common military weapons in the world and has been used by the U.S. Military in Afghanistan, Iraq, and other parts of the world. As of 2013, Heckler & Koch replaced the original HK416 with the A5 variant.
