The Level III+ Lightweight Hard Armor Plate from Level 4 Armor combines a silicon carbide strike face bonded to a UHMWPE backer in a stand-alone 10" x 12" plate weighing approximately 3.9 lbs. Rated Special Threat Level III+, it stops rifle rounds up to and including 7.62x54R-L at 2,840 fps and covers the full range of common intermediate and full-power cartridges shown in the ballistic table below. One plate per unit; a standard two-plate chest rig runs approximately 7.8 lbs in ballistic weight.

Who this is for

• Civilian home defenders and range shooters who want rifle-rated protection at a weight that doesn't sacrifice mobility during extended wear
• Armed professionals and security personnel needing stand-alone Level III+ coverage without relying on a soft armor backer
• Budget-conscious buyers seeking a silicon carbide composite plate that addresses M855/SS109 green-tip and mild steel core threats often excluded from standard NIJ Level III ratings

Ballistic performance

Silicon carbide is a hard ceramic that fractures and defeats rifle projectiles on impact. The UHMWPE composite backer captures the fragments and spreads residual energy across the panel. Together they produce a plate that handles both high-velocity 5.56 threats and heavier 7.62 projectiles while keeping weight near the 4 lb mark.

This plate is rated Stand Alone, meaning it stops the listed threats without a soft armor backer installed behind it. The Level III+ designation covers threats beyond the standard NIJ Level III round set, specifically including M855/SS109 green-tip and 7.62x39 mild steel core rounds that standard Level III plates are not tested against.

Ballistic test data

Plate compatibility and cut geometry

This plate ships in a single 10" x 12" size. The cut and curve geometry are not specified by the manufacturer; contact us to confirm fitment with your specific plate carrier before ordering. The 10x12 format is the most common plate pocket dimension and seats correctly in the vast majority of plate carriers designed for that size.

Specifications

Fit and carrier compatibility

The 10" x 12" plate size fits plate carriers with a standard 10x12 plate pocket. Shooters Cut, SAPI Cut, and square-cornered pockets all accommodate this footprint, though corner clearance varies by carrier model. If your carrier uses a different plate pocket size or you are stacking a soft armor backer behind this plate, contact us before ordering to confirm the fit.

Frequently asked questions

What rounds does this plate stop?

This plate stops 7.62x63mm JSP, 7.62x54R-LPS and L, 7.62x51mm M80, 7.62x39mm mild steel core and ball, 5.56x45mm M193, and 5.56x45mm M855/SS109 green tip. Full velocities for each round are listed in the ballistic table above.

What is the difference between Level III, Level III+, and Level IV?

Standard NIJ Level III plates are tested against six rounds including 7.62x51mm M80 ball. Level III+ is a vendor-defined designation indicating coverage of additional threats such as M855/SS109 green tip and 7.62x39 mild steel core that fall outside the standard Level III test suite. Level IV is NIJ-standardized and covers armor-piercing 30-caliber M2 AP at 2,880 fps. This plate is rated Level III+, not Level IV, and is not tested against M2 AP.

Is this plate NIJ Listed or NIJ Certified?

This plate carries a Special Threat Level III+ designation. The Level III+ rating is a vendor-defined special threat classification, not a separate NIJ standard. It is not currently listed on the NIJ Compliant Products List for Level III+ as no formal CPL category exists for that designation. Buyers who require a CPL-listed plate should look at Level III or Level IV options with confirmed CPL entries.

Does this plate need a soft armor backer?

No. This is a Stand Alone plate, meaning it defeats the listed threats without a soft armor backer installed. Adding a soft armor panel behind it can reduce backface deformation further, but the plate performs to its rated threat levels on its own.

How heavy is a two-plate setup?

Each plate weighs approximately 3.9 lbs, so a standard front-and-back configuration runs approximately 7.8 lbs in plate weight before adding the carrier, accessories, or side plates.

Can this plate be shipped to my state?

Body armor cannot be shipped to New York or Connecticut due to state-level restrictions on civilian body armor sales. Outside those states, this plate ships to all US addresses. Under 18 U.S.C. § 931, anyone with a federal felony conviction for a crime of violence is prohibited from purchasing or possessing body armor.
