This video demonstrates a ballistic test of a Level 3 polyethylene body armor plate against M855 ammunition. The test confirms that while the plate meets Level 3 requirements against certain threats, it is penetrated by M855 rounds due to their hardened steel core. The speaker, an experienced firearms instructor, highlights the limitations of poly plates against specific ammunition types.

Quick Summary

Level 3 polyethylene body armor plates can be penetrated by M855 ammunition due to its hardened steel core. While meeting Level 3 requirements against some threats, poly plates have limitations against specific rounds like M855, which can defeat the material.

Frequently Asked Questions

Can Level 3 body armor stop M855 ammunition?

According to this ballistic test, a Level 3 polyethylene (poly) body armor plate was penetrated by M855 ammunition. This is due to the hardened steel core of the M855 round, which is capable of defeating poly materials despite not being classified as armor-piercing.

What is the difference between M193 and M855 ammunition regarding body armor?

M193 is a standard round often used for Level 3 plate testing, typically fired at over 3200 fps from a 20-inch barrel. M855, however, has a hardened steel core that poses a greater threat to polyethylene plates, as demonstrated by its penetration in this test.

What are the limitations of polyethylene body armor plates?

A primary limitation of polyethylene (poly) plates is their inability to consistently stop certain rifle rounds, particularly those with hardened steel cores like M855. While they offer good protection against many threats and are lightweight, their effectiveness can be ammunition-dependent.

What does the penetration into a concrete backer signify in body armor testing?

The deep penetration into a concrete backer after a round passes through body armor signifies the amount of kinetic energy transferred. This indicates the potential for significant blunt force trauma and secondary injuries to the wearer, even if the plate itself stops the projectile.
