The Barrett M82, standardized as the M107 by the US Military, and the Barrett M107 are both powerful .50 caliber sniper rifles developed by Barrett Firearms. While they are quite similar in terms of appearance and functionality, there are some key differences between the two weapons.

1. Design and Construction

The Barrett M82 and the Barrett M107 share the same basic design principles as semi-automatic, recoil-operated sniper rifles. However, the Barrett M82 is generally considered the earlier model, with the Barrett M107 being an improved version.

2. Weight and Length

The Barrett M82 has a weight of approximately 29.7 pounds (13.5 kg) without optics, while the Barrett M107 is slightly heavier at around 33.7 pounds (15.3 kg) without optics. Additionally, the M82 is 48 inches (121.9 cm) long, whereas the M107 measures 57 inches (144.8 cm) in length. The differences in weight and length can affect portability and ease of use in various situations.

3. Effective Range

Both rifles have an effective range of around 1,800 meters (1.1 miles), with some sources suggesting the M107 may have a slightly longer effective range due to its improved accuracy. However, it is important to note that variations in ammunition, environmental conditions, and shooter capability can also impact the effective range of both rifles.

4. Muzzle Velocity

The muzzle velocity refers to the speed at which the bullet exits the barrel. The Barrett M82 has a muzzle velocity of approximately 853 meters per second (2,800 feet per second), while the Barrett M107 has a slightly higher muzzle velocity at around 930 meters per second (3,050 feet per second). The higher muzzle velocity of the M107 can result in improved ballistic performance.

5. Recoil Management

Both rifles are known for their manageable recoil considering their powerful caliber. However, the Barrett M107 is reported to have better recoil management over the M82. The design improvements in the Barrett M107, such as a more effective muzzle brake and enhanced recoil-absorbing materials, contribute to better recoil control and shooter comfort.

6. Component Materials

The Barrett M82 utilizes a mix of steel and aluminum in its construction, while the Barrett M107 features an upgraded receiver made from a single piece of forged aluminum alloy. The use of premium materials in the M107 reduces weight and enhances overall durability.

7. Rail Systems

Both rifles incorporate Picatinny rail systems for attaching various accessories such as optics, bipods, and other auxiliary equipment. However, the Barrett M107 features an extended top rail that allows for greater flexibility in mounting additional accessories.

8. Military Adoption

The Barrett M82 was originally developed for military use and gained significant recognition during the Gulf War. In 2002, the US Military officially standardized the rifle as the M107, recognizing its improved features and design enhancements.

Overall, the Barrett M107 is considered an upgraded version of the Barrett M82, featuring improvements in weight, length, recoil management, muzzle velocity, and component materials. While both rifles serve the same purpose as powerful anti-material sniper rifles, the Barrett M107 offers enhanced performance and user comfort.
