In 2010, the US Marine Corps adopted the HKM27 as its new Infantry Automatic Rifle (IAR). The rifle is named for the 1st Marine Division, 2nd Battalion, 7thRegiment, that tested the rifles and IAR (infantry automatic rifle) concept for more than a decade. Replacing the M249 for rifle squads, the M27 was once declared, "The most tested weapon in the history of the Marine Corps". The M27 has proven itself again and again, from the test ranges at Twenty nine Palms to the Global War on Terror - and beyond. With its precision, durability, and reliability, the M27 expanded beyond the initial role of IAR. The M27 is fielded today as an IAR, precision rifle, general infantry rifle, and most recently as a short-barreled upper receiver Reconnaissance Weapons Kit (RWK). Now civilians can own a piece of Marine Corps history with a limited - run HKMR27, a civilian - legal tribute to the M27. The MR27 uses the same HK DNA and offers the battlefield - proven reliability, durability, and precision of a worthy homage to such a proven military rifle.
