m27 vs m16
Because of that, the Marine Corps issued a request in early 2017 for 11,000 M27 IARs from H&K. The M27 IAR, when fully outfitted, is about a pound heavier than an M4/M4A1 (note: the M4A1 is slightly heavier than the M4). The thicker M27 barrel can fire longer than the M4 before overheating, but will also disperse heat longer. Follow Task & Purpose on Twitter. In 1999, a Universal Need Statement was issued for an Infantry Automatic Rifle (IAR). It was also significant that the Army had chosen not to pursue the IAR concept.[6].
One M38 marksman version, fitted with a scope and QDSS suppressor, is to be fielded per infantry squad to hit targets at 600 meters. [15], After the Marine Corps Operational Test and Evaluation Activity conducted further testing at MCAGCC Twentynine Palms, Fort McCoy and Camp Shelby (for dust, cold-weather, and hot-weather conditions, respectively), limited fielding of 458 IARs began to four infantry battalions (one per each Marine Expeditionary Force, one reserve) and one light armored reconnaissance battalion, all of which deployed to Afghanistan in 2011. Further, the SAW was already a battle-proven weapon. The M249 is first and foremost a machine gun and is accurate to about twelve minutes of angle, meaning rounds will hit within a foot of their target at 100 yards. It is used by the United States Marine Corps and is intended to enhance an automatic rifleman's maneuverability. Fast forward to 2017. The most glaring problem with the M249: it was never a good institutional fit for the Marine Corps. For decades the fire team automatic rifleman has been equipped with the M249 Squad Automatic Weapon. It is a 3.5×35 machine gun optic that has a Ruggedized Miniature Reflex (RMR) sight screwed on top for close-quarters engagements under 100 meters. While the M249's volume of fire may be greater, it is less accurate. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4. In 1999, a Universal Need Statement was issued for an Infantry Automatic Rifle (IAR). Former SAW gunners initially did not like the M27, but appreciated it as time went on. The magazine well has a flared opening that aids in magazine insertion, but a PMAG 30 GEN M2 magazine cannot be inserted due to the frontal plastic bevel on the PMAG. The rifle barrel is slightly longer and heavier than the M4 carbine, giving the M27 a slight range advantage over the carbine. Also, enemy snipers and other personnel may be less likely to identify the Automatic Rifleman — that’s a good thing. [2], While Marine Corps Systems Command was optimistic about operational testing, former Marine Commandant General James T. Conway remained skeptical because of the reduction in firepower at the fireteam-level that would result if the M27 was adopted.
[22], Marines issued with the M27 enjoy its familiarity with the M4-style weapons in service. Experienced troops who have dealt with incoming fire are less likely to take cover from incoming rounds if they are not close enough. By contrast, the M249 it replaces is primarily an area suppression fire weapon with no precision fire capability. )", "Corps chooses H&K to make SAW replacement", "Conway eyes additional testing for auto-rifle", Marines swap firepower for accuracy with IAR, "SAW replacement set for real world testing", "Infantry Automatic Rifle: Update on a Marine Corps Priority Weapon System", "Corps to Replace SAW With Automatic Rifle", Marines want 11,000 Infantry Automatic Rifles to replace M4 in every infantry squad, "Corps may field infantry auto-rifle this fall", West Coast Marines complete first M27 Designated Marksman Course, IAR wins over skeptical Marine infantrymen, M249 Light Machine Gun: Endangered species for Marines in Afghanistan, Marine brass endorses infantry plan to ditch M16 for M4, "Deadlier rifles and ammo may be on the way", "U.S. Marine Corps Selects Heckler & Koch Infantry Automatic Rifle (HK IAR) Candidate as Replacement for FN M249 SAW/LMG", No More M4 — USMC Adopts H&K M27 Infantry Automatic Rifle, The Corps' quest for the best rifle for infantrymen, Marine Corps bans popular rifle magazines, Magpul speaks out on the Marine Corps polymer magazine ban, Army Round Triggers Problems in Marine M27 Auto Rifle, Marines to Get PMAG to Fix M27 Woes with M855A1 Round, Marine Unit in Norway First to Deploy with Rifle Suppressors, The Marine Corps Plans on Fielding Suppressors to Infantry Squads Starting this Year, "US Marine Corps Selects Leupold Scope for M38 Designated Marksman Rifle", USMC Fields Heckler & Koch M27 as M38 Designated Marksman Rifle, The Corps is on track to fully field the M38 marksman rifle, despite setbacks for the M27 IAR, "H&K wins Marine Corps IAR contract with HK416 variant", United States Navy press release regarding Contract #3928, "Heckler-Koch HK M27 IAR Infantry Automatic Rifle (USA / Germany)", "The Infantry Automatic Rifle: Closing the last 5 yards", United States Marine Corps Squad Advanced Marksman Rifle, United States Army Squad Designated Marksman Rifle, https://en.wikipedia.org/w/index.php?title=M27_Infantry_Automatic_Rifle&oldid=987138168, Weapons and ammunition introduced in 2010, Articles with dead external links from January 2018, Articles with permanently dead external links, Short description is different from Wikidata, Wikipedia articles incorporating text from the United States Marine Corps, Creative Commons Attribution-ShareAlike License, 36.9 to 33 in (940 to 840 mm) w/adjustable, This page was last edited on 5 November 2020, at 04:18. A 2006 report conducted by the CNA Corporation found that among U.S. Army combat veterans, the M249 scored below average in third place (after the M16 rifle and M4 carbine, but generally ahead of the M9 pistol) in handling, accuracy, maintainability and corrosion resistance. "The new pre-solicitation notice of 50,184 [M27s]," said Woodburn, "is [meant] to up the production capacity that H&K must be able to meet as the sole-source provider [of the M27], should the Marines decide to order more in the future."
The Marine Corps Warfighting Lab (MCWL) conducted a large-scale test of future concepts which focused on the 3rd Battalion, 5thMarines during a deployment cycle. The M27 has become so well liked in August 2017 the Marine Corps issued an intent notice to procure another 50,000 rifles—enough to equip every infantryman and automatic rifleman in front-line combat units. Fielding of the approximately 6,500 M27 units was expected to be completed in the summer of 2013, at a cost of $13 million. After reading the article, “The Marine Corps’ Rifle is Super Expensive – And No One Knows Why,” I spent a few days pondering my response. Ammunition consumption went up, the weight of carried ammunition went up, and accuracy went down—not an ideal situation for infantry. [6], The Infantry Automatic Rifle program began on 14 July 2005, when the Marine Corps sent Requests For Information to arms manufacturers.
[4][22] It is issued with the Vickers Combat Applications sling and rail sling mounts, AIM Manta Rail Covers, Harris bipod, KAC backup iron sights, a foregrip, and bayonet lug. Those M16A4s can go away. - 7 Veteran-Friendly Manufacturers That Are Hiring, - The 6 Types Of Contractors You Encounter Overseas, - Here’s How Marines Fared On The New Physical Fitness Test, © Copyright 2020 Center for the National Interest All Rights Reserved, 7 Veteran-Friendly Manufacturers That Are Hiring, The 6 Types Of Contractors You Encounter Overseas, Here’s How Marines Fared On The New Physical Fitness Test. This has all been released to the public and has been discussed ad nauseum on Task & Purpose, The Firearm Blog, Soldier Systems Daily, and others for at least a year and a half, and I’m shocked that T&P did not include this in their recent article. In contrast, the USMC considers 3 MOA to be “normal” for an M4/M4A1 when it’s new (although many group better than that). You can follow him on Twitter: @KyleMizokami. The battalion leadership also saw the M27 as better at preventing collateral damage, as it is more controllable on fully automatic than the M249. As an Enlisted Marine, he served as an Anti-Armor Marine, a Scout-Sniper, and Sniper Instructor. Don't let the critics tell you otherwise. The increase in ammo consumption meant an increase in carried ammunition weight. I have spent almost ten years working to improve the USMC infantry rifle, and I think this article gets it largely wrong about the M27 Infantry Automatic Rifle.
[29], The M27 usually draws ammunition from a standard 30-round STANAG magazine. [20] He felt that, while more accurate, it was unlikely that the M27 could provide fire-superiority over the belt-fed M249 SAW. Thread pitch diameter, major diameter and minor diameter for M profile external threads are given. Those will be re-purposed to Marines across the MAGTF so that they can benefit from a rifle the USMC and US Army have already proven superior to the M16A4. [6][7], In 2006, contracts were issued to several manufacturers for sample weapons.
Around 2000, the 1st Marine Division’s 2nd Battalion, 7th Marines Regiment conducted initial, limited IAR trials which confirmed the desirability of a light automatic rifle. The longer relief helps reduce injury risk from recoil. He, and all Federal Acquisitions professionals like him, are subject to oversight and scrutiny unlike most any other field in the service. [15], The M27 is essentially an HK416 with accessories required by the Marine Corps.
