![]() Some HK416 variants also have “OTB” (over-the-beach) capability and can be safely fired after being submerged in water and not completely drained. The highest quality steel is used in this unique manufacturing process producing a barrel that provides superior accuracy with minimal degradation of accuracy and muzzle velocity. The HK416 uses a barrel produced by Heckler & Koch’s famous cold hammer forging process further improving reliability, service life, and operator safety during obstructed bore occurrences or in extreme extended firing sessions. It also reduces operator cleaning time, heat transfer to the bolt and bolt carrier, and wear and tear on critical components. This increases the reliability of the weapon and extends the interval between stoppages. The HK-proprietary gas system uses a piston driven operating rod to control the function of the bolt, preventing propellant gases and the associated carbon fouling from entering the weapon’s interior. Both are free-floating and do not touch the barrel or negatively affect the weapon’s accuracy. These HK rail systems can be installed and removed without tools. Both are designed by HK and allow all current accessories, sights, lights, and aimers used on M4/M16-type weapons to be fitted to the HK416. Upgrades were made to the internal operating system and various component parts, improving reliability in best and worse case scenarios, with all types of ammunition, with all barrel lengths, and with and without sound suppressors attached.Ĭhoice of handguards include the HK free-floating 4-quadrant rail system (FFRS) and a modular rail system (MRS). Army Desert Proving Ground in Yuma, Arizona revealed multiple areas for weapon improvement. Input from the users of current M4/M16-type arms, high-speed video assessment, and extensive live-fire testing in extreme operational environments such as the U.S. The origins of the HK416 began with the realization of the deficiencies of the direct gas impingement (gas tube) operating system found on conventional M4/M16-style weapons. Marine Corps an their new M27 Infantry Automatic Rifle (IAR) - an innovative program to create a highly accurate, lightweight, and more reliable alternative to many of Marine Corps’ currently fielded light machine guns. ![]() And in 2011, this HK416 variant was selected by the U.S. In April 2007, this HK416 was selected as the new Norwegian Army rifle. The HK416 has been combat-proven in Southwest Asia and has also gained worldwide attention of military, law enforcement, and security users. Using the HK-proprietary gas piston system found on the G36, the HK416 does not introduce propellant gases and carbon fouling back into the weapon’s interior, making it the most reliable of any M4/M16 type weapon. special operations forces as a major product improvement of M4/M16-type carbines and rifles. Heckler & Koch developed the HK416 for U.S. This HK416 variant with the longest barrel length the 20 inch model is suitable for use as a precision rifle.
