What Rifle Does the Marine Corps Use?

The United States Marine Corps has a long history of relying on rifles to provide effective firepower for its infantry and special operations forces. For decades, the M16A2 has been the standard-issue rifle for the Marine Corps, but recent developments have led to a shift towards the M27 Infantry Automatic Rifle (IAR). In this article, we will explore the evolution of the Marine Corps’ rifle selection, the advantages and disadvantages of the M16A2 and M27, and the reasons behind the transition to the M27.

History of the Marine Corps’ Rifle Selection

The Marine Corps has a rich history dating back to 1775, and during that time, it has relied on various rifles to equip its infantry. The first standard-issue rifle was the Model 1816 Springfield Rifle, which was used throughout the 19th century. In the early 20th century, the Marine Corps adopted the M1903 Springfield Rifle, which was used during World War I and World War II.

In the 1950s and 1960s, the Marine Corps transitioned to the M14 rifle, which was designed to fire the 7.62x51mm NATO cartridge. However, the M14 proved to be heavy and bulky, leading to the development of the M16A1 in the 1960s. The M16A1 was designed to be lighter and more compact, with a collapsible stock and a smaller caliber cartridge (5.56x45mm).

The M16A2: A Decade of Service

The M16A2 was introduced in the 1980s as an upgrade to the M16A1. The M16A2 featured a new heavy barrel, a collapsible stock, and a fixed carrying handle. It also had a redesigned trigger and a more ergonomic grip. The M16A2 was widely used by the Marine Corps during the Gulf War and the early 1990s, but it began to show signs of wear and tear due to its extensive use.

The M27 Infantry Automatic Rifle (IAR)

In the early 2000s, the Marine Corps began to look for a new rifle to replace the M16A2. The M27 IAR was developed as a response to the need for a more versatile and effective rifle. The M27 is a 5.56x45mm cartridge rifle designed to provide suppressive firepower and to support the squad-level tactics.

Advantages of the M27

The M27 has several advantages over the M16A2:

• Increased magazine capacity: The M27 has a 30-round magazine, compared to the 20-round magazine of the M16A2.
• Improved ergonomics: The M27 has a more ergonomic grip and a redesigned trigger, making it more comfortable to shoot and more accurate.
• Increased durability: The M27 has a heavier barrel and a more robust construction, making it more durable and resistant to wear and tear.
• Better suppressive firepower: The M27 has a higher rate of fire and a larger magazine capacity, making it more effective at providing suppressive firepower.

Disadvantages of the M27

The M27 also has some disadvantages:

• Increased weight: The M27 is slightly heavier than the M16A2, which can make it more difficult to carry.
• Limited accuracy: The M27 has a shorter barrel than the M16A2, which can affect its accuracy at longer ranges.

Transition to the M27

The Marine Corps began transitioning to the M27 in 2008, and by 2010, the M27 had become the standard-issue rifle for all Marine Corps infantry units. The transition was largely successful, with Marines reporting improved accuracy, reliability, and durability with the M27.

Conclusion

The Marine Corps has a long history of relying on rifles to equip its infantry, and the M27 IAR has become the latest standard-issue rifle for the Corps. While the M16A2 served the Marine Corps well for decades, the M27 offers improved ergonomics, increased magazine capacity, and better suppressive firepower. The transition to the M27 has been largely successful, and the rifle has become an essential tool for Marine Corps infantry units.
