assault rifle was developed by Heckler & Koch company in
the 1990s to meet US Army's Delta Force requirement. It is and
improved version of the
carbine, that is widely used by the US military. However the HK416
is independently made and modified. Originally it was marketed as
& Koch M4, but the name was changed after Colt threatened H&K
with legal action over trademark
infringement. Still though this weapon is sometimes unofficially referred as HK M4, or
German M4 carbine.
In 2004 this weapon was adopted by the Delta Force, where it
replaced the M4 carbine. Currently the HK416 it is used by
more than 20 countries, including Australia, Francem Georgia,
Indonesia, Irealand, Italy, Japan, Jordan, Malaysia, the
Netherlands, Norway, Poland, the Philippines, Serbia, Singapore,
Slovakia, South Korea, Turkey and the United States. It is mainly by special forces, law enforcement
forces and civilian government agencies. Despite that the HK416 is
the primary service rifle of the Norwegian armed forces.
is worth noting, that a couple of years earlier the Heckler & Koch company successfully
improved the British Army
assault rifle and cured a lot of its problems.
In terms of appearance the HK416 resembles the M4. Due to similarity
it has a familiar feel for soldiers, reducing the time needed for
retraining. However the safety and reliability margins of the HK416
are significantly increased over the M4 and
The HK416 is a gas-operated automatic weapon. Internally it is
similar to Stoner-designed weapons, such as the
the HK416 uses a
patented gas piston system, derived from the
& Koch G36 assault rifle, which is more reliable. This new operating system
significantly reduced malfunctions and increased life of parts,
comparing with the original Colt M4 carbine. During tests in 60 000 total rounds the HK416 had 233
stoppages, while the M4 had 882 stoppages.
Due to the
different operating system the HK416 can safely be fired when
drenched with water, or even while fully-submerged. A water-logged
M4 or M16 would explode if fired. It has also been reportedly
demonstrated that the HK416 will safely fire even when dragged
through fine sand and mud. In similar conditions the M4 is likely to
jam before firing 10 rounds. While the M4 will not cycle ammunition
efficiently (in some cases, not at all) at some angles, notably
while upside-down, the HK416 will operate normally at any

comes as standard with diopter-type iron sights. It also has a
Picatinny-type scope rail and can be used with various scopes.
Furthermore there is accessory rail on all four sides of the

HK416C ultra-compact assault rifle with a 228 mm (9 in) barrel. It
has a different side-folding buttstock.
HK416D a modified variant. It was introduced in 2010. In 2011 it has
been adopted by US Marine Corps as the
M27. Marines initially ordered 4 748
rifles and planned
to obtain a total of 6 500 of these automatic rifles. These partially replaced
the M249 light machine gun.
HK416N, a version for Norwegian armed forces. After extensive
evaluation it was adopted as a standard issue rifle with Norwegian
HK416A5, a proposed version for the US Army to replace the M4
carbine. It has a different stock and some other modifications, such
as ambidextrous fire controls. This
weapon can be used with sound suppressor. It entered the US Army's Individual Carbine competition,
however eventually the competition was cancelled and no weapon was
chosen. Even though the HK416A5 has become the standard model that
is being proposed for military and law enforcement use.
HK417 is an enlarged version of the HK416, chambered for
NATO 7.62x51 mm ammunition. This weapon is a battle rifle, rather
than assault rifle. It has a longer range due to its full-power
