![]() The M249 is gas operated and air-cooled, it has a quick-change barrel (allowing the gunner to rapidly replace an overheated or jammed barrel), and a folding bipod attached to the front of the weapon (an M192 LGM tripod also being available). The M249 provides infantry squads with a high rate of machine gun fire, combined with the accuracy and portability of a rifle. The weapon was introduced in 1984 after being judged most effective (compared to a number of candidate weapons) to address the lack of automatic firepower in small units. The M249 is manufactured in the United States by the subsidiary FN Manufacturing LLC, a company in Columbia, South Carolina, and is widely used in the U.S. The M249 light machine gun ( LMG), also known as the M249 Squad Automatic Weapon ( SAW), which continues to be the designation that FN America uses, and formally written as Light Machine Gun, 5.56 mm, M249, is the American adaptation of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN). ![]() Iron sights or Picatinny rail for various optics M27 linked disintegrating belt in a 100- or 200-round soft pouch In spite of all these differences, both the M4 and M27 use the same ammunition, so the introduction of a new weapon to a large part of the Marine Corps in battle should not cause too many complications, and the military can keep both rifles in service at the same time. The accessories that go with the gun include a Trijicon ACOG Squad Day Optic and a folding bipod. Also, the barrel is free-floating, meaning it makes contact with the rest of the rifle only at the receiver, and this reportedly prevents the gun’s accuracy from degrading as the weapon heats up over repeated firing.Īll of these attributes make the weapon accurate by up to 550 meters – 90 meters further than the M4. Its slightly longer and thicker barrel gives it extra range and the gun has less chances of overheating when compared to the M4. It recycles hot gases right back into the action to cycle the bolt.Īpart from the way the M27 fires, its accuracy reportedly makes it a lot more attractive. ![]() As a result, the M27 is a cleaner, ‘cooler to the touch’ rifle. The M27 uses a piston operating system, while the M4 Carbine has a gas impingement system. The differences between the rifles, however, are all internal, specifically in the way the bolt is driven. Manufactured by Heckler & Koch, the M27 is a 416 assault rifle that is similar in its outward appearance to the M4 Carbine. He also added that Javelin anti-tank missile operators and mortarmen would continue to use M4s for now. General Robert Neller, Commandant of the Marine Corps, said that “forward observers, fire support teams and engineers” are also appropriate candidates for the M27, apart from Marines in the infantry squad. The M27 is famed for its capacity to fire accurate, short bursts of suppressive fire at the enemy at distances that are more than what was achievable by the M249 which is a less accurate but fast-firing and high-capacity weapon. According to reports, every Marine in an infantry squad will get this weapon. ![]() The M27 Infantry Automatic Rifle will be given to Marines in combat-related operations.Īlmost all frontline Marines will get an M27, reported .uk, as they have found this rifle sufficiently better than the M4 – enough to cough up the additional cost of $3,000 per rifle. The Marine Corps has decided to increase its usage of the M27 automatic assault rifle and will begin issuing the upgraded weapon in place of the ageing M4 Carbine. The US Marine Corps adopted the M27 in 2010, but was only provided to one Marine per infantry fire team, or three per squad, and was supposed to replace the M249 SAW at the time. Heckler & Koch’s M27 is considered to be the heir of the M4 rifle. The M4 first got entered service at 1994, but it is based on the M16A2 that has been around since the 1960s. The US Marine Corps has been using the long time running Colt M4 carbine rifle.
