About

Maximum Rifle-Rated Protection with Lightweight Options Level 4 body armor, also called Level IV body armor or rifle plates, is the highest rifle-rated protection the NIJ writes a standard for. Our Fortis IV/RF3 Multi-Curve plate delivers multi-hit, UHMWPE-core Level IV protection from $199.95, stopping armor-piercing rounds like .30-06 M2 AP. Every plate here is tested to meet, or certified to, the NIJ 0101.06 Level IV standard, so families, travelers, and prepared citizens can build a rifle-rated loadout with confidence. Pair a plate with a carrier and you’re ready for the most extreme common rifle threats. Plates are sold individually. What Does Level 4 Body Armor Stop? Level 4 body armor is built to stop the heaviest rifle threats the NIJ rates. Under the NIJ 0101.06 standard, a Level IV plate must stop a hit from .30-06 M2 armor-piercing (AP) ammunition. In practice, a plate that defeats M2 AP also stops lower-energy rifle rounds such as 5.56 M855 (“green tip”), 7.62x39, and 7.62x51 (.308), along with all handgun threats.
