Can Level III+ Body Armor Survive M855A1?

Published on September 24, 2021
Duration: 14:04

This video provides an expert-level evaluation of RMA Armament's Model 1091 Level III+ body armor, testing its resilience against high-power rifle rounds like M855A1, 7.62x54R, and .30-06 M2 AP. The assessment, conducted by Iraqveteran8888, highlights the critical role of standoff distance in armor performance and demonstrates that while Level III+ can stop some unrated threats, specific rounds like M855A1 can penetrate, especially at closer ranges. The analysis emphasizes understanding armor limitations beyond official NIJ ratings.

Quick Summary

Level III+ body armor can stop M855A1 rounds at longer distances (e.g., 200 yards) where velocity is reduced. However, M855A1 successfully penetrated the RMA Armament Model 1091 plate at closer ranges (muzzle distance and 100 yards) due to its hardened steel penetrator, highlighting the importance of understanding armor limitations beyond official NIJ ratings.

Frequently Asked Questions

Can Level III+ body armor stop M855A1 rounds?

Level III+ body armor, like the RMA Armament Model 1091 tested, can stop M855A1 rounds at longer distances (e.g., 200 yards) where velocity is reduced. However, M855A1 successfully penetrated the plate at closer ranges (muzzle distance and 100 yards) due to its hardened steel penetrator.

What is backface deformation in body armor testing?

Backface deformation is the inward displacement of the armor material on the side opposite the impact. Even if a projectile is stopped, significant backface deformation can cause severe blunt force trauma, potentially leading to serious injury or death.

Does standoff distance affect body armor performance?

Yes, standoff distance significantly affects body armor performance, especially against threats the armor is not officially rated for. Reduced projectile velocity at greater distances can allow armor plates to stop rounds that would penetrate at closer ranges.

What are the limitations of Level III+ body armor?

Level III+ body armor is typically rated for threats like M193, M855, and 7.62x39 MSC. It may not reliably stop advanced rounds like M855A1, particularly at closer ranges, and can experience severe backface deformation from rounds like 7.62x54R.
