The M855A1 is a high-performance ammunition round that has revolutionized the landscape of military cartridges. From its inception to its widespread adoption, this ammo has undergone significant advancements, offering enhanced performance and capabilities compared to its predecessors. Let’s delve deeper into what makes the M855A1 so unique and sought after.

Product overview on M855a1 For Sale

The M855A1 has a copper-jacketed steel core, differing from the previous M855 round which has a lead core. The so-called “green ammo” not only has increased penetration of armor and hard targets, but allows the Army to be more environmentally friendly on its ranges and training environments.

The M855A1 is optimized for the shorter-barrel M4 where the standard M855 was optimized for the M16. The powder burns faster and creates more pressure, and has the effect of reducing flash. The round yaws like the M855, but its yaw is more consistent and predictable, meaning its terminal effects are not yaw dependant.

The Army plans to replace its entire inventory of M855 rounds with the M855A1 round.

Breif History about the M855a1

In 1982, the Army adopted the 5.56mm M855 round to replace the M193 in an effort to achieve better performance at longer ranges with the M249 Squad Automatic Weapon (SAW). A steel penetrator in the front end of the M855 provides increased hard-target performance.

History and Development

The development of the M855A1 traces back to the need for a more effective and versatile ammunition round. It evolved from the original M855, also known as the “green tip,” which served as the standard NATO round for decades. However, advancements in materials and ballistics prompted the U.S. military to seek an improved version.

Nevertheless, the controversy continued over which caliber was better-5.56mm vs. 7.62mm-as the magazine noted through the years. In 1982, a review by Army Research, Development, and Acquisition Magazine (as it was then called) of small-arms ammunition development praised the lighter weight and lesser recoil achieved with the smaller round, yet observed that, “One of the inferiorities is, however, its penetration capability.”

In 1982, the Army adopted the 5.56mm M855 round to replace the M193 in an effort to achieve better performance at longer ranges with the M249 Squad Automatic Weapon (SAW). A steel penetrator in the front end of the M855 provides increased hard-target performance.

Development of the M16A2 rifle, which matched the twist of the M249 SAW, also allowed use of the heavier M855 round. The M193 is still produced today, largely for foreign military sales.

From 2003 to 2006, the Army conducted a study of available bullets, commercial and military, and found none that provided improved perforA,A!mance over the M855 against the target sets required of a general-purpose round.

Ensuring Consistency and Environmental Responsibility

In post-combat surveys and field reports from Iraq and Afghanistan, most Soldiers have indicated that the round works fine, delivering the desired effects against threat targets. But some Soldiers have reported that the round did not perform consistently, causing concern in the ammunition community.

Composition and Design Features

Core Material

Unlike its predecessor, the M855A1 ammo features a solid copper core instead of the traditional lead core. This enhances its penetration power and terminal ballistics, making it more effective against various targets.

Jacket Material

The M855A1 utilizes a steel-tipped projectile with a copper jacket, providing superior armor-piercing capabilities while maintaining stability and accuracy during flight.

Penetrator Design

One of the key innovations of the M855A1 ammo is its hardened steel penetrator, designed to penetrate hardened targets such as body armor and light vehicles with exceptional efficiency.

Ballistic Performance

The M855A1 ammo boasts impressive ballistic performance, characterized by high velocity, energy, and penetration power. Its flat trajectory and consistent accuracy make it a preferred choice for military operations requiring precision and reliability.

Military Adoption and Use

Since its introduction, the M855A1 has been widely adopted by military forces around the world, including the U.S. Army and Marine Corps. Its effectiveness in various combat scenarios has solidified its reputation as a top-tier ammunition choice for modern warfare.

Advantages of M855A1 Ammo

  • Enhanced penetration capabilities
  • Improved terminal ballistics
  • Consistent accuracy and reliability
  • Reduced lead contamination

Comparison with Other Ammunition

Compared to traditional ammunition rounds, the M855A1 offers superior performance in terms of penetration, accuracy, and lethality. Its advanced design and construction set it apart from conventional options, making it the preferred choice for military applications.

Controversies and Criticisms

Despite its numerous advantages, the M855A1 has faced criticism and controversy, particularly regarding its environmental impact and potential health risks associated with its lead-free composition. Additionally, concerns have been raised regarding its compatibility with certain firearms and the potential for barrel wear over time.

Civilian Availability

While primarily designed for military use, civilian versions of the M855A1 are available on the market. However, legal restrictions and regulations may vary depending on the jurisdiction, limiting its accessibility to the general public.

So what makes the EPR so good’ It uses the same components as the M855-a jacket, a penetrator, and a metal slug. But the new round contains some subtle changes (see Figure 1). The copper cup, from which the jacket is formed, is reverse-drawn, the opposite of how the M855 jacket is drawn. The hardened steel penetrator is almost twice as heavy as the one used in the M855 and is fully exposed instead of hiding beneath the softer copper jacket.
