Heckler & Koch HK 416

Heckler & Koch HK 416 History

Heckler & Koch introduced the HK416 series automatic rifles in 2005 as a potential replacement for the M4 series carbines. The HK416 is a joint American and German effort to produce a more reliable and modern replacement for the M4 carbine. Development began in 2004, and the U.S.

Army-flagged Special Forces Delta Force was the first to deliver the weapon and phase out its M4.

Externally, the HK416 looks like the M16 assault rifle of its smaller cousin, the M4 carbine. The pistol grip, trigger group and magazine feeder are all contained under the body of the weapon. The feed system accepts 20- or -30-round M16 STANAG magazines, and 100-round Beta C-Mag drums. The magazine release is located on the upper right of the magazine casing, while the fire selector lever is located on the left side of the lower casing (fire mode shown as a pictogram). The weapon fires 5.56x45mm NATO cartridges, which are gas operated using a rotating bolt.

Rates of fire from 700 to 900 rounds per minute are possible (depending of course on ammo type and barrel length). The barrel is free-floating and can fire over 20,000 rounds before it needs to be replaced. In fact, released video shows Heckler & Koch's gunmaker testing the HK416 with around 10,000 rounds of ammunition in fully automatic fire, with the system never disturbed. The screws themselves are cool to the touch, allowing the operator to operate the components with bare hands without injury.

The sighting device includes a rear rotation diopter type and an anterior column. The HK416 will feature a MIL-STD-1913 modular Picatinny rail system, allowing it to use the same upgrades and accessories as the M16 and M4. The foregrip can be mounted in front of the magazine feeder. Axes are collapsible and expandable if needed.

The HK416 can be shot out of the water without sacrificing performance.

One of the HK416's strengths is its new gas system, which was developed from the system of the Heckler & Koch G36 assault rifle. The HK416 uses a short stroke piston drive rod that moves the bolt backwards. This closed action reduces heat build-up along the bolt carrier assembly and prevents gas from entering the interior of the gun. The end result is a reliable and long-range weapon system worthy of military use. The short stroke gas piston system contrasts with the direct impact system used in the base M16 rifle.

The new system is designed to extend the life of the inner workings of the weapon while reducing breakdowns when firing in the field.

The HK416 series consists of sub-variants called D10RS, D14. 5RS, D16. 5RS and D20RS - Their main difference is the length of the barrel, their respective lengths are indicated in their names (10", 14.5", 16.5" and 19.9" respectively). The D10RS weighs 6.7 pounds, while the D20RS weighs 8.5 pounds.

HK417 was developed by Heckler & Koch based on the new HK416. It is designed as a larger system that can fire 7.62x51mm NATO cartridges.

MR223 and MR308 became civilian evolutions of HK416 and HK417 respectively. Both weapons were released in 2007 with some modifications for the more limited civilian market, including a semi-automatic fire mode and other changes.

By 2009, the new Heckler & Koch designations MR556 and MR762 were applied to these two civilian models.

The HK416 family of operators (as of this writing) include France, Germany, Indonesia, Netherlands, Norway, Poland, Slovenia, Turkey and the United States.

While serving in France, the HK416 has replaced the FAMAS series for special forces. The Germans added HK416 to their special forces, as did Indonesia. The Dutch Army has replaced their C8 rifles with the HK416 system. Norway signed a contract in 2007 for 8,200 HK416 rifles. At the time of writing, this weapon is being used by the Polish military and security organizations.

The U.S. military and selected security and police groups have evaluated the weapon. Turkey will take over licensed production of the HK416 under the name "Mehmetcik-1".

HK416 originally carried the Heckler & Koch name HK M4. Apparently, the folks at Colt Defense, who made the M4 carbine, weren't happy with it. A trademark infringement lawsuit was filed, and Heckler & Koch later changed the name of the new gun to HK416.
