ESRT Body Armor

Rifle-rated protection is so thick and heavy. No one has cracked the code for high threat protection with concealment. Until now. The ESRT body armor plate (Enhanced Special Rifle Threat) brings lightweight minimalism to high performance rifle protection.

At just five-pounds (size medium) and only a half-inch thick, this highly concealable multi-curve special threat plate also defeats the most prevalent and dangerous rifle rounds worldwide.

Defeating common and uncommon munitions from the world’s most common rifle threats–AR-15 and AK-47 platforms–the ESRT Special Threat Plate additionally stands up to multiple impacts from M855A1 and 7.62X39 API-BZ.

All while staying hidden under common street clothing. For those operating in non-permissive environments, there’s never been a higher level of protection available in such a thin and also lightweight package.

More Than Concealable

For military & law enforcement users, the RMA ESRT Special Threat Plate is also the thinnest and lightest way to add high threat multi-hit protection from AR-15 and AK-47 platforms into your standard IIIA soft armor vest.

Plus, civilians have a better way to maintain a low profile under your clothing or in your backpack while staying protected from criminal elements operating with high-grade weaponry. Additionally, combine the ESRT special threat plate with our 0214 IIIA panels for full RF2+ protection.

Is ESRT Body Armor Level III?

The ESRT Special Threat Plate doesn’t fit the mold of other plates, because it isn’t like other special threat plates. While the NIJ Level III standard requires six impacts of (very rare) 7.62X51 M80 NATO Steel-jacketed rounds, it doesn’t require common penetrator threats like M855 that easily defeat Level III plates and can be found in any American gun store.

What about RF2?

But when the NIJ looked to revise their rifle protection standards, they still missed more modern domestic threats like M855A1 and common foreign threats like 7.62X39 API-BZ.

Level III+ plates are too thick to conceal due to the NIJ steel-jacketed M80 testing standard–a round you’d be hard-pressed to find anywhere outside of foreign NATO military arsenals.

Additionally, it’s already been made obsolete and replaced by the M80A1 in US military stockpiles. It simply doesn’t make any sense to use with real-world armor testing. Plainclothes operators working foreign or domestic areas shouldn’t have to choose one threat or the other. Low visibility doesn’t have to also mean low protection.

For those facing high threat intermediate rifle cartridges from AR-15 and/or also AK-47 platforms–penetrator or not–the ESRT Special Threat Plate is the ultimate in low-visibility armor.

Whether defending from enemies foreign or domestic, there is no better low-signature option than the ESRT. There simply isn’t any other special threat plate that’s as thin, light, and also multi-hit capable.
