The U.S. Army’s Most Lethal Sniper Rifles

Few weapons command as much respect and awe in the world of military precision as the sniper rifle. The U.S. Army, known for its cutting-edge arsenal, has three standout performers that have earned their place among the elite: the M24, Mk-22, and M110. 

These rifles aren’t just tools. They embody American military innovation and are the backbone of long-range combat strategy. But what makes these rifles so special, and how do they compare to each other?

When it comes to tried-and-true performance, the M24 Sniper Weapon System (ref) stands in a league of its own. Introduced in 1988, this bolt-action rifle has become synonymous with long-range accuracy and reliability. 

Based on the venerable Remington Model 700, the M24 has seen action in numerous conflicts, earning a reputation as a marksman’s best friend.

Adaptability & Longevity of M24

The M24’s long action, originally designed to accommodate larger cartridges, has proven to be a versatile platform. While initially chambered for the 7.62×51mm NATO round, its design allows easy reconfiguration to more powerful calibers. 

This foresight has extended the M24’s service life, allowing it to adapt to evolving battlefield needs.

Enter the Barrett Mk-22 (ref) MRAD (Multi-Role Adaptive Design), the latest addition to the Army’s sniper arsenal. Selected in 2019 as part of the Advanced Sniper Rifle program, the Mk-22 represents a leap forward in sniper rifle technology. 

Its modular design allows quick barrel changes and caliber conversions, making it a true multi-mission platform.

The Mk-22’s versatility is its greatest strength. Capable of firing 7.62×51mm NATO, .300 Norma Magnum, and .338 Norma Magnum rounds, this rifle can adapt to various engagement distances and target types. 

With an effective range exceeding 1,500 meters, the Mk-22 pushes the boundaries of what’s possible for a shoulder-fired weapon.

Rapid Engagement Capabilities of M110

The M110 Semi-Automatic Sniper System (SASS) (ref) reigns supreme in rapid engagement. Based on the AR-10 platform, this rifle bridges the gap between precision and volume of fire. 

Its semi-automatic action allows snipers to focus on the target while cycling to the next round, a crucial advantage in dynamic combat situations.

The M110’s design is specifically suited to urban warfare and medium-range engagements. With a maximum effective range of 0.49 to 0.62 miles, it excels in scenarios where targets may present themselves quickly. 

The rifle’s compatibility with night vision devices and suppressor-ready barrel make it a versatile tool for covert operations.

Mission-Specific Selection

While each rifle excels in its own right, the choice often comes down to mission-specific requirements. The M24’s bolt-action reliability suits situations demanding absolute precision and minimal mechanical interference. 

The Mk-22’s adaptability shines in varied environments where engagement distances change rapidly. Meanwhile, the M110’s semi-automatic capability gives it an edge in urban combat and situations requiring quick follow-up shots.

The U.S. Army’s investment in these three platforms underscores the continuing importance of skilled marksmen in modern warfare. Despite advancements in drone technology and long-range missiles, the human element – embodied by the sniper – remains a critical component of military strategy. 

These rifles, each representing a different approach to precision shooting, ensure that Army snipers are equipped to handle any situation they might encounter on the battlefield.
