The M27 Infantry Automatic Rifle is a variant of the HK416. The HK416 was originally developed by Heckler & Koch for U.S. special operations forces as a major product improvement of M4/M16-type carbines and rifles. Using the HK-proprietary gas piston system found on the company’s G36 rifle, the HK416 prevents propellant gases and carbon from fouling the weapon’s interior, making it the most reliable of any M4/M16type weapon. During the last decade, the HK416 has been combat-proven in Southwest Asia and has also gained the attention of military, law enforcement, and security users outside of the U.S. In April 2007, the HK416 was selected as the new Norwegian Army rifle. The HK operating system, as well as other improvements made to various components and parts ensure reliability and performance in all scenarios, with all types of ammunition, with all barrel lengths, and with and without sound suppressors attached. An innovative free-floating four-quadrant rail system/ handguard designed by HK allows all current accessories, sights, lights, and aimers used on M4/M16-type weapons to be fitted to the HK416. This HK rail system handguard can be installed and removed without tools. The HK416 uses barrels produced by Heckler & Koch’s famous cold hammer forging process. The highest quality steel is used in this unique manufacturing process producing a barrel that provides superior performance with minimal degradation of accuracy and muzzle velocity even after thousands of rounds are fired. Many HK416 variants also have “OTB” (over-the-beach) features and can be safely fired after being submerged in water and not completely drained. In addition to the improvements in the baseline weapon, HK has produced corrosion resistant steel and polymer magazines and a proprietary buffer to further enhance functional reliability.
