Corps Set to Field SAW Replacement
July 01, 2010


The Marine Corps will field its new, lightweight auto rifle this fall to five combat battalions preparing for war-zone deployments.

Commandant Gen. James T. Conway gave Corps officials the green light in April to issue approximately 450 M27 Infantry Automatic Rifles, enough to replace every M249 squad automatic weapon in four infantry battalions and one light armored reconnaissance battalion.

The limited fielding is a final test to find out if the Heckler & Koch-made weapon performs as well in an operational environment as it has in testing, said Charles Clark III, who oversees infantry weapons requirements at the Corps' Combat Development and Integration office at Quantico, Va.

"The battlefield test will be a verification of what we have already established through extensive operational testing," Clark said. "We want to get a user assessment prior to full-rate production."

Conway's decision comes despite his past concerns about replacing the M249 with a magazine-fed automatic rifle. His main worry is whether the M27's light weight and accuracy will be enough to make up for the loss of suppressive firepower Marine gunners will give up when they go into battle without the belt-fed M249.

Program officials acknowledge that a 30-round magazine cannot produce the high volume of fire the M249 is capable of when loaded with a 200-round belt. The Corps is considering high-capacity magazines that can hold 50 or 100 rounds of 5.56mm ammo, but Marines that deploy with this first batch of IARs will carry only 30-round magazines.

"The initial limited fielding will not include a high-capacity ammunition source, but that remains an option," Clark said, explaining that such magazines will have to undergo a separate round of testing.

The M27, a variant of the H&K 416, weighs just 7.9 pounds, unloaded. By comparison, the M249 weighs 17 pounds, unloaded.

Marines involved in operational testing at Twentynine Palms, Calif.; Fort McCoy, Wis.; and Camp Shelby, Miss., were "very comfortable with it because it's a lot like a M16A4 and it's far more maneuverable and portable" than the M249, Clark said. "The H&K gun has performed very well throughout operational testing."

Marine officials selected the H&K weapon in October over two prototypes from Colt Defense LLC and one made by FN Herstal. (Colt makes the M4 and FN makes the M249.) The M27 uses a short-stroke gas piston, which proved more reliable than the M16/M4's direct gas system in an Army dust test in late 2007.

The new IAR, which fires from the closed-bolt position, is most effective when employed as a point-target weapon, program officials maintain.

"The accuracy has been a real standout," Clark said. "The IAR has demonstrated to be a far more accurate gun" than the M249, which fires from the open-bolt position.

In the defensive role, the M27 used "far less" ammunition to drop the same number of targets compared to the M249, Clark said.

Program officials maintain that the increased accuracy will compensate for the M27's slower, sustained rate of fire. Unlike the M249, the new IAR doesn't have a spare barrel that can be switched out to prevent overheating. Marine gunners will have to keep their sustained rate of fire at 65 rounds per minute compared to the M249's 85 rounds per minute.

"It has a little bit lower sustained rate of fire, but it's far more accurate," Clark said.

The Corps hopes to begin fielding the M27s in November so Marine units have "four to six months" to train with their new weapons.

"We are not sending these guns straight to Afghanistan," Clark said. "The units that are participating will have the guns long before they go into theater."

Each company in the three active infantry battalions and one reserve infantry battalion will receive 28 M27s, one for every SAW gunner and one extra to remain organic to the unit. These companies will also retain six M249s to give commanders more firepower if necessary, Clark said.

The LAR battalion will receive 14 M27s per company and will not retain any M249s.

The Corps plans on buying 4,476 M27s and reducing its number of M249s from 10,000 to approximately 8,000, Marine officials said.

But that adjustment will not happen until Conway sees the results from the user assessment, Clark said, adding that it could be late next summer before the feedback is collected from theater.

Marine Corps requirements officials hope that Conway will decide whether to take the weapon into full-rate production by late 2011.

"We are confident that the gun we have tested is a good gun, but the final decision rests with the commandant of the Marine Corps," Clark said.

Let's see... No spare barrel. 30 rnd magazine. By definition this weapon is incapable of effective suppressing fire.

Why is this called a squad support weapon again?

Might as well bring back the full auto function to the M-16 if we're going to do this.

I have a feeling they are doing it to sneak some better rifles in rifleman......

Its comparable to a m16/m4......closed bolt, no quick swap barrel, small magazine......

Invent a new classification for a rifle to get around red tape possibly?????

Should of learned from us Brits.

LSW = shit, then designated as a marksman rifle because of its longer, heavy barrel and now not used cause its rubbish.

The thing is, there's a company trying to rush th Corp into buying it's 150 rd spring fed drum. I watched a video on it with the M27, and it actually looks fucking badass! They showed a man firing from the knee on full auto and I'm impressed. Mind you, I consider myself an expert SAW gunner, having humped one through 2 full tours in Iraq and having qualified expert 4/5 time at the range. I would rather shit on an M-4/M-16 versus trusting my life to one, but the M27 looks like a good idea with the 150 rd drum.

If the Corps is smart, they'll buy the drum and issue it out immediately.

Here, I did you guys one better.

This calmed my fears. Let's hope the USMC buys this drum.

Remember that they were also looking into the Ultimax m100 some time ago. Wanting rifleman to have 100+ rds at their disposal instead of 30......I can see this weapon and its classification as an IAR as a way to get around red tape

Well I hope they're serious about incorporating the 150 rnd drums, because otherwise all we've done is come up with a 21st Century BAR... And one that doesn't even come close to hitting like a BAR, either.
