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.

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.”

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.

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.
