Heckler & Koch was awarded a competitive contract to produce the U.S. Marine Corps’ new Infantry Automatic Rifle (IAR). The formal “Full Rate Production” announcement by the Marines caps a competition that began more than three years ago. Designated the M27 Infantry Automatic Rifle, the lightweight, 11.62 pounds weapon with ancillary equipment, is a variant of the highly successful Heckler & Koch HK416 used by military, law enforcement, and special operations units in the U.S. and throughout the world. The M27 IAR replaces the heavier, M249 SAW (Squad Automatic Weapon) which has been used by the Marines in Infantry Squads since the mid-1980s in the automatic rifle role. Both weapons fire the 5.56 mm NATO cartridge. The five-year, indefinite delivery, indefinite quantity contract calls for possible delivery orders up to $23,600,000 for the production, delivery, and associated support of the Marines’ Infantry Automatic Rifle program. The Marine Corps approved the full rate production and fielding of the M27 Infantry Automatic Rifle during the summer of 2011. There will be one M27 IAR per four-man fire team, with three M27 IARs per squad, 28 per company and more than 4,000 across the entire Marine Corps. hk-iar “After a rigorous testing process, both in garrison and deployed environments, and in-depth consultation with weapons experts through the Corps, the commandant approved the fielding of the M27 Infantry Automatic Rifle,” said Marine spokesman Major Joseph Plenzler in a press statement in June. “The fielding of the IAR will significantly enhance the ability of our infantrymen to gain and maintain fire superiority, reduce their fighting load and provide them a more ergonomic and accurate weapons system that can keep up during the assault.”


“Winning the Marine’s IAR competition is another milestone for our HK416,” said Wayne Weber, President of Heckler & Koch USA. “Developed at no cost to the U.S. taxpayer and with U.S. military input in the aftermath of the September 11th attacks on America, the HK416 competed against—and beat many worthy challengers. This contract award is a direct testament to the superior performance of the HK416 and it is an honor for Heckler & Koch to equip the Marines with such a fine rifle.” Source: HK

    I am a member of the United States Air Force and im in the security forces. Why in earth would you replace the saw with this? I don’t need a heavy version of my M4A3…. I pity you marines. Hope it works like they say it does.

  • I don’t get it. How is this an “improvement”. What bunch of retiring generals are getting their pockets lined this time: uniforms, weapons, etc. The ‘tip of the spear’ suffers because of general staff kooks.

    Really? Millions of dollars of testing and this is what they come up with? Apparently the board that approved this was never in Iraq or Afghanistan where a 200rd drum is very handy! I 30 round or even 100 round mag plain sucks not to mention all A4’s/M4’s should offer select fire, full auto fire anyway, this is an upgrade mechanically over the SAW however lower ammo capacity is a HUGE detriment. Should have stepped up to the ACR…Semper Gumby though right, OOrah Marine Corps…glad Im out…

    Well its not necessarily a heavy m16, because it’s based on the hk 416 (obviously stated) which is piston driven and not the direct gas impingement or whatever so therefore more reliable, easier to clean etc. but yes they could have done better and i think they should have went with the .308 (7.62X51mm NATO) round.

  • Shadowlord521

    A heavy barreled m4 with full auto capability, crap. Come on they could have done better with a much more potent round. If not, make all m4s or m16s heavy barreled and full auto because thats all it is

  • Chris Grimes

    Still going to keep that crap round .556 for a squad type auto weapon….

  • mike

    I hope the warfighter lab in Q town will provide the new 100rd surefire mags with this new HK

  • josh

    thank god the saw sucked i hated having it and it was worthless it about time the did this i have been saying it for years.

    I would have thought the military world would have learned enough lessons from the British fielding the Bren LMG during WW2. As good as it was (being used all the way up to the Falklands engagement) it was seriously limited as a suppressive fire weapon because it was magazine fed. How long do you think it will take for individual marines to buy and equip the new weapon with 100 rd. BETA C mags?

    A twelve pound M16! HaHaHa! Stoner would crap his pants. The BAR weighed just eight pounds more, was lethal to 1000 yards, and is almost 100 years older. I guess that’s progress.
