The DKX M3 Series ballistic plates are NIJ 0101.06 level III certified stand-alone protection with multi-strike capability, in an unbelievably light-weight package. This high molecular weight polyethylene plate enhances mobility for the operator.

The M3 also stops special, non-armor piercing threats, such as the Winchester Ranger and 7.62x39 MSC. The positive buoyancy of the M3 plates provides users in maritime environments added support and flotation, while a rigid polycarbonate backing gives superior blunt force trauma protection.

Each DKX M3 Series plate comes equipped with Radio Frequency Embedded Verification (RFEV) tracking for inventory management along with an industry first 7 year warranty. Applies only to certified plate sizes.

We offer standard sized shooter and full cuts on our website, other sizes and cuts are available. Please reach out to us at and we can help you find exactly what you are looking for.

American-Made Quality

Phalanx Systems produce all of its plates in the U.S.A. in its own facility to ensure that you are getting the highest quality product that will protect you when you need it most. There plates go through routine testing at an NIJ approved laboratory so they can guarantee protection against specific threats.

Phalanx is on a mission to protect our protectors, and they proudly provide armor to first responders, law enforcement and military agencies. Phalanx Defense Systems provide you the same high quality armor that they trust to protect themselves.

Multi-Hit Tested

Each plate is tested to withstand multiple hits without being compromised. We believe these devices should be worn to save lives, and Phalanx Defense Systems want to give our customers the highest level of protection that makes sense for their situation.


Priced With You In Mind

Cheap body armor is likely made of cheaper material, made outside of the United States or made in facilities that are not well equipped.

Some competitors’ best selling plates are ‘in conjunction’ plates, where purchasing means you will need to invest in additional soft panels or hard armor to reach the protection level you are trying to achieve. All plates made by Phalanx Defense Systems are Stand Alone Plates that provide all of the protection you are seeking at a reasonable price.

Light & Buoyant Armor

DKX plates are made from 100% Dyneema® ballistic material, which is the world’s strongest fiber™. That, combined with a polycarbonate backing in a proprietary press and manufacturing process, has created some of the lightest armor on the market available to most budgets.

The armor’s backing provides an added level of protection against trauma upon impact, while also making the plate positively buoyant* to help the wearer in emergency water situations.


Unprecedented Warranty

Industry average warranty for hard armor plates is 5 years. Phalanx Defense Systems’ most popular plates (M2, M3, M7X) have a 7 year warranty, one of the longest warranties on the market. Our plates are more protected from the elements and daily wear-and-tear than our competitors with their special coating. We want you to make your investment in the best product and know that it will last you for years to come.
