This listing is for a limited-edition civilian version of a USMC Deployment Kit. The MR27 is the civilian version of the legendary M27. The M27 Infantry Automatic Rifle (IAR), a specific variant of the HK 416, was selected by the U.S. Marine Corps in August 2011 in an innovative program to develop a highly accurate, lightweight, and more reliable alternative to currently fielded light machine guns. The "M27" designation represents a tribute to the 2nd Battalion, 7th Marine Regiment which is the unit that devised the original concept of the Infantry Automatic Rifle. The Infantry Automatic Rifle program began in 2001 as a "needs statement" within the Marine Corps. Operational experience in Iraq and Afghanistan in the last several years reinforced the requirement. The program called for a magazine-fed 5.56 mm automatic rifle designed to be operated by a single Marine and possessing greater accuracy, increased reliability, and lighter weight than the existing belt-fed 5.56 mm machine gun. These factors would enhance the automatic rifleman's maneuverability and speed to either augment and/or replace the belt-fed M249 Squad Automatic Weapon (SAW). As recent testing and operational deployment has confirmed, the IAR is more readily adapted for house-to-house clearing operations and day-to-day employment by the automatic rifleman when compared to an M249.
