RMA 1165 Level 4 plate test.

Published on December 1, 2024
Duration: 20:12

This video provides a comprehensive test of the RMA 1165 Level IV ballistic plate, demonstrating its performance against various threats including handgun rounds, 5.56mm projectiles (M193 and M855) from different barrel lengths, .30-06 ball, and M2 AP rounds. The instructor, Chris from Regular Guy Training, emphasizes the plate's lightweight design and its ability to meet and exceed NIJ standards, particularly regarding backface deformation.

Quick Summary

The RMA 1165 Level IV ballistic plate is rated for multiple strikes from 30-06 armor-piercing rounds and meets NIJ standards. It is also the lightest Level IV plate from RMA, significantly reducing wearer fatigue. During testing, it successfully stopped multiple M2 AP rounds at 15 yards, though significant backface deformation occurred.

Frequently Asked Questions

What is the RMA 1165 Level IV plate rated for?

The RMA 1165 Level IV plate is rated for multiple strikes from 30-06 armor-piercing rounds. It is designed to meet NIJ standards, which typically involve testing at a distance of 15 meters.

How does the RMA 1165 plate perform against M2 AP rounds?

The RMA 1165 plate successfully stopped multiple M2 AP rounds fired at 15 yards, even when clustered tightly. While significant backface deformation occurred, it prevented full projectile penetration on initial impacts.

What is the significance of the RMA 1165's lightweight design?

The RMA 1165 is noted as the lightest Level IV plate from RMA, with a set weighing approximately 2 lbs less than traditional Level IV plates. This reduction in weight significantly alleviates shoulder fatigue during prolonged wear.

What is backface deformation and how does it relate to the RMA 1165 test?

Backface deformation is the displacement of the armor material on the side opposite the impact. While the RMA 1165 showed deformation, it remained within levels considered safe by NIJ standards, meaning it would likely cause injury but not penetration.
