Bullet Proof Plates Levels

Quick Answer

Ballistic plate levels describe the specific rifle threats a plate is tested to resist. Under the current National Institute of Justice (NIJ) system, the rifle protection levels are RF1, RF2, and RF3. Older plates may instead carry Level III or Level IV labels. The label is a starting point: the exact model, tested ammunition, and required wearing configuration matter too.

Level III and RF1

Under the older NIJ 0101.06 standard, Level III plates were tested against a specified 7.62×51 mm rifle round. The newer RF1 category adds specified 7.62×39 mm and 5.56 mm M193 test rounds. RF1 is the current category most closely associated with Level III, but the test threats are not identical. A plate labeled Level III should therefore not be assumed to stop every rifle round, including every type of 5.56 mm ammunition.

RF2

RF2 is an intermediate category introduced under the newer system. It includes the RF1 test threats and adds a specified 5.56 mm M855 round. This gives buyers a defined NIJ category for that additional threat. You may also see plates advertised as “Level III+,” but that is not an official NIJ protection level; check the manufacturer’s test documentation to learn what a particular plate was tested against.

Level IV and RF3

Under NIJ 0101.06, Level IV armor was tested against a specified .30-06 armor-piercing round. RF3 is the corresponding category in the newer naming system and also uses a specified .30-06 M2 armor-piercing test threat. Neither label means a plate will stop every armor-piercing round under every condition. Protection claims should be tied to the exact ammunition and testing requirements.

What to Check Before Choosing a Plate

First, identify which NIJ standard appears on the product label: 0101.06 or 0101.07. Then confirm the model’s status on the NIJ Compliant Products List if NIJ certification is claimed. Review its weight, size, fit, and instructions as well. A standalone plate is designed to provide its stated protection without separate soft armor; an in-conjunction-with (ICW) plate requires the specified soft-armor backing. The tested configuration is part of the protection claim.

The best plate is one whose documented protection matches the threats you need to address and whose size and weight allow it to be worn correctly. Explore American Blast Systems’ ballistic plate options and review each model’s specifications before selecting your setup.
