The HK416 is an assault rifle designed and manufactured by Heckler & Koch. It is a modified version of the American M4 carbine with many changes, most notably a new gas operating system from the Heckler & Koch G36. Customers have the option of purchasing a new upper receiver, buffer and drive spring to refurbish M4s or buying a completely new build HK416.
Delta Force replaced its M4s with the HK416 in 2004 after tests revealed that the piston operating system significantly reduces malfunctions while increasing the life of parts. The HK416 has been tested by the United States military and is in use with some law enforcement agencies and special operations units. It has been adopted as the standard rifle of the Norwegian Armed Forces as well.
A modified variant is undergoing testing by the United States Marine Corps as the M27 Infantry Automatic Rifle. 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), limited fielding began for 458 IARs to four infantry battalions (one per each Marine Expeditionary Force and one reserve) and one light armored reconnaissance battalion; all are slated to deploy to Afghanistan in 2011.
In December 2009, a modified version of the HK416 was selected for the final testing in the Infantry Automatic Rifle program, designed to partially replace the M249 light machine gun at the squad level for the United States Marine Corps. It beat the three other finalists by FN Herstal and Colt Defense. In July 2010, the HK416IAR was designated as the M27, and 450 were procured for additional testing.
The Norwegian Army made an extensive evaluation before selecting the HK416 as its new primary firearm.
The HK417 is a larger version of the HK416 chambered for the full-size 7.62x51mm NATO rifle cartridge.
Civilian variants of the HK416 and HK417 were announced in 2007, named MR223 and MR308. Both are semi-automatic rifles with several 'sporterized' features. At the 2009 SHOT Show, these two firearms were introduced to the American civilian market renamed respectively MR556 and MR762. There is another variant of the MR556 called the MR556A1, which is an improved version of the former. It was created with input from American special forces units.
The HK416C ultra compact variant of the HK416 has been introduced in October 2010. The HK416C has a high degree of component commonality with the HK416 family though the HK416C has a new retractable butt stock and buffer system. According to its specifications the HK416C, with its very short barrel for the 5.56x45mm NATO chambering, can be expected to produce muzzle velocities of approximately . The firearm's precision is specified as ≈ 4 MOA (12 cm at 100 m) by Heckler & Koch. The philosophy behind the ultra compact HK416C variant has similarities with the Heckler & Koch G36C subcarbine, which was developed out of the G36 assault rifle, and the XM8 Compact Carbine design. The intended purpose of subcarbines is to provide operators with a weapon of (nearly) submachine gun or personal defense weapon size, but firing standard military rifle cartridges, for scenarios such as VIP protection, urban warfare, and other close quarters battle (CQB) situations.
