In this comprehensive guide, we will delve into the history, design, features, and capabilities of the Heckler & Koch M27 IAR, as well as its adoption and use by the US Marine Corps.
History and Development
The development of the M27 IAR began in the early 2000s, when the US Marine Corps initiated the Infantry Automatic Rifle (IAR) program. The goal of the program was to create a more accurate, reliable, and lightweight automatic rifle that could provide a high volume of suppressive fire in various combat environments.
Heckler & Koch, in collaboration with the US Marine Corps, developed the HK416 IAR, which would later become the M27 IAR. The rifle was designed to be more accurate and reliable than the M249 SAW, while also being lighter and more maneuverable.
In 2010, the US Marine Corps officially adopted the M27 IAR as a replacement for the M249 SAW in certain infantry units. The rifle has since seen extensive use in combat environments, including in Afghanistan and Iraq.
Design and Features
The M27 IAR is a gas-operated, select-fire rifle that uses a piston-driven system to cycle the action. The rifle features a free-floating barrel, which provides improved accuracy and reduced heat buildup.
One of the key features of the M27 IAR is its use of a STANAG 4179 magazine, which is also used by the M16 and M4 rifles. This allows for greater interoperability between units and reduces the logistical burden of maintaining multiple types of ammunition.
The M27 IAR also features a folding stock, which allows the rifle to be more easily stowed and transported. The stock is adjustable for length of pull, and the rifle also features an adjustable cheekpiece.
