The goal of this project was to enhance the Automatic Rifleman's maneuverability and displacement speed, while providing the ability to suppress or destroy those targets of most immediate concern to the rifle team.
Marine Corps Systems Command (MARCORSYSCOM), Infantry Weapons Systems, Quantico, Virginia announced plans on 19 November 2007 to conduct a limited competition for the second phase (production) of the Infantry Automatic Rifle (IAR) project. The IAR shall possess a robust, detachable, collapsible, and adjustable bipod.

The IAR shall be capable of both semi-automatic and full automatic firing. The IAR shall accept and function with the current Marine Corps service rifle (the M16A4) 30 round magazines. The magazine shall permit rapid visual determination of the number of rounds remaining (Objective). The IAR shall utilize a magazine with a capacity of 100 rounds (Threshold). (Sustained rate is defined as the rate at which a weapon can fire indefinitely without experiencing a major malfunction such as a cook-off or a significant degradation in accuracy.) The IAR shall be capable of a sustained rate of fire of 36 rounds per minute (Threshold), 75 rounds per minute (Objective).
The IAR shall possess a military standard 1913 rail interface. The IAR (excluding the magazine and accessories) shall weigh less than 12.5 pounds empty (Threshold), 10.5 pounds (Objective). A threshold criterion is defined as a mandatory requirement and an objective criterion is defined as a desirable (but not mandatory) requirement. Some attributes include threshold and objective criteria. The IAR would replace the infantry’s M249 Squad Automatic Weapons (SAWs) with an automatic rifle easily operable by a single infantry Marine that emphasizes lightweight and portability in order to maximize dismounted maneuverability. The IAR would enable the fire team to rapidly suppress point and area targets of immediate concern. In July 2005 the United States Marine Corps sought information for a non-developmental, 5.56mm, Infantry Automatic Rifle (IAR). The “automatic rifleman” equipped with an actual automatic rifle is a proven concept that was first introduced in 1918 and solidified in 1944 when the first similarly equipped and structured 13-man Marine Rifle Squad was authorized. Light machinegun- A belt-fed automatic weapon, with a removable barrel, designed to be carried and employed by an individual – with or without an assistant – from a bipod and / or an assault fire posture, in the direct infantry support role. This select-fire capability, as well as the use of magazine-fed rifle ammunition, differentiates it from a machinegun and submachine gun. In order to truly understand the subtle, but important doctrinal differences between the two weapons, and where some confusion may have existed, the definitions of each must be examined.Īutomatic Rifle - A self-loading, fixed barreled rifle chambered for a rifle cartridge, capable of delivering both semi and fully automatic fire. The M-249 SAW is a light machinegun that was tasked with filling the role of the automatic rifle. The M27 is an Automatic Rifle and it sets the conditions for small unit movement in a completely different manner than its predecessor, the M-249 Squad Automatic Weapon.

Built with a Free Floating Rail System there is no contact between the barrel and Rail system except for at the base of the receiver. The IAR’s pusher rod gas system directs 95% of propellant gases and fouling out of the muzzle, allowing the weapon to remain virtually carbon free for hundreds of rounds. This allows the user to engage with precision, and switch to suppressive fire, or vice versa, as needed.Ĭompared to the M249, the reduction in weight allows the user to be more agile in today’s aggressive fight. It operates in semi-automatic and automatic modes of fire. The M27 Infantry Automatic Rifle (IAR) is a lightweight, aircooled, pusher rod gas operated, magazine fed, shoulder fired weapon. The M27 Infantry Automatic Rifle was adopted by the Marine Corps in 2011 and replaced the M249 light Machinegun as the “Squad Automatic Weapon”. The Corps plans to field the M27 more broadly in infantry units as early as 2018. Marine Corps Systems Command is purchasing M27 IARs from a single source vendor based on feedback from Marines.
