US Marines say the BAR is Reborn!

Weapons: The BAR Reborn


The BAR Reborn

November 22, 2010: The U.S. Marine Corps has bought
4,200 new light machine-guns. The new weapon, the M27, will replace the current
M249s in marine infantry battalions. However, each of these battalions will
retain six M249s, to give the battalion some options. The marines will withdraw
from service 20 percent of their 10,000 M249s by the time all 4,200 M27s have been delivered.

The M27 is a 3.6 kg (7.9 pound, empty) automatic weapon based on the HK416.
It has a forward grip and heavier barrel and can use a 30 or 100 round magazine.
Unlike the M249, it does not have an easily replaceable barrel, but it is more
accurate and has a slower rate of fire (560-640 rounds per minute).

The M27 uses a mechanical system that is less likely to jam,as well as a floating barrel (for better accuracy.) Marines are expected to use fewer rounds of more accurate fire with the M27 than they did with the M249.

The M27 came after five years of research and development to
create a weapon that would replace the M249, which the army and marines began using in the early 1980s. The marines have had a lot of complaints about the M249 in Iraq (jams from all the dust and sand), and many of the marine M24s are simply wearing out.

The marines were originally looking for an IAR (Infantry Automatic Rifle)
that weighed between 4.8 kg (10.5 pounds) and 5.7 kg (12.5 pounds) empty, used a large magazine (100 rounds or more) as well as the standard M-16 30 round magazine. The heavy barrel on the IAR had to be able to handle sustained fire of 36-75 rounds a minute. The higher number was the ideal. It had to have the standard rail on top for mounting accessories, be resistant to jamming from dust and sand and, in general, be a lot better than the M249. The marines always
planned to buy 4,000 weapons initially, and wanted to do so as soon as
possible.

The M249 weighs 6.8 kg (15 pounds) empty, and has been popular with the
troops. But in over two decades, despite several tweaks to the basic design,
many complaints have piled up. The marines were not the first ones to take
action on a replacement. Six years ago SOCOM (U.S. Special Operations Command) began using the Mk 46 LMG (Light Machine Guns). This weapon is a modified
version of the American M249 squad automatic weapon (SAW), which is in turn a
modified version of a European design from the Belgian firm FN. The Mk 46 is
lighter, at 5.9 kg (13 pounds) empty, 8.2 kg (18 pounds) loaded, with 200
rounds, compared to 10 kg (22 pounds) for the M249. The Mk 46 also has the rail
on top for the quick attachment of sights and such. The lighter weight was
accomplished with a newly designed barrel, and removing various bits of hardware SOCOM didn't want. Added is a forward pistol grip and a detachable bipod. SOCOM likes to use the Mk 46 more like a "heavy assault rifle" than a "light
machine-gun."

U.S. Army Special Forces pioneered the development of the 5.56mm light
machine-gun four decades ago, when they obtained the first experimental models
for use in Vietnam. The Special Forces and SEALs were very impressed with the
light weight, and heavy firepower, from these weapons. But it took over a decade
for the regular army to adopt such a weapon, mainly in response to the success
the Russians were having with their own version of the lightweight squad
machine-gun.

The army is also making noise about an M249 replacement, and have followed
the marine search with great interest. The marines finally selected the lighter
HK entry after three months of field testing. The M27 is quite similar to the
first American "light machine gun", the M1918 BAR (Browning Automatic Rifle).
This was a 7.62mm, 7.25 kg (16 pound) automatic rifle, similar in appearance to
the later (1950s), and lighter M-14. The BAR was revolutionary in World
War I, and was used by the United States until the 1960s, when it was replaced
with 6.6 kg M-14A1s equipped with a heavier barrel. This was not a satisfactory
solution, and led to the development of the M249.

Interesting - it weighs about the same as an M16 and 2 lb more than a M4. My (uninformed) suspicion is that the Marine Corps are stealthily replacing the M4 with this new assault rifle by callin it a "light machine gun". Any informed views?

[BlueSkyJaunte]

It's just an H&K 416, which is just a piston-operated M4.

But apparently in recent military trials the M4 jammed a lot more than either the HK416 or the FN SCAR?

Amusingly, from Wikipedia:

In July 2007, the US Army announced a limited competition between the M4 carbine, FN SCAR, HK416, XCR, and the previously-shelved HK XM8. Ten examples of each of the four competitors were involved. Each weapon fired 60,000 rounds in an "extreme dust environment." The purpose of the shoot-off was for assessing future needs, not to select a replacement for the M4.[6][7] The XM8 scored the best, with only 127 stoppages in 60,000 total rounds, the FN SCAR Light had 226 stoppages, while the HK416 had 233 stoppages. The M4 carbine scored "significantly worse" than the rest of the field with 882 stoppages.

So the 416 came in 3rd in the first round of trials. My understanding is that the SCAR has already been given the boot, for some reason. ($?)

despite HK heritage,hk performance, its still a pip squeak .223 round. a real BAR was 30.06 and was devastating.


they would have been better served with buying a HK21E or variant as it has a quick change barrel, 7.62 x 51 ballistics, and it can be box fed,mag fed, or BELT FED!



and since im the taxpayer and want the MOST BANG FER BUCK.................just who in the hell spec'd a pip squeak .223? again.



a semi auto REAL BAR is available for around $4700 bucks w/bakelite furniture or wood furniture.


the hk 416/417 ran circles around the m4 in field tests but was rejected due to costs. once again lowest bid.


and thats how our military works aside from lowest bid, it must be produced in the u.s..
