Frequently Asked Questions About Bullet Proof Helmets

❓ What is a bulletproof helmet made of?

Bulletproof helmets are typically made of Kevlar®, UHMWPE (Ultra High Molecular Weight Polyethylene), aramid fibers, or advanced composite materials. These materials are layered and molded to absorb and disperse the energy from ballistic threats like handgun rounds and shrapnel.

❓ Can a bulletproof helmet stop an AK-47 or rifle round?

Most standard ballistic helmets are rated to NIJ Level IIIA, which means they can stop handgun rounds up to .44 Magnum but not high-velocity rifle rounds like 7.62mm or 5.56mm. Some advanced models (with add-on plates or enhanced composite designs) may resist certain rifle threats, but they are rare and typically heavier.

❓ What is backface deformation and why does it matter?

Backface deformation refers to how much the helmet bulges inward when it stops a bullet. Even if the round doesn’t penetrate, a deep indentation can cause concussions or skull fractures. NIJ standards require that this bulge does not exceed 25mm, ensuring the wearer is protected from both penetration and blunt trauma.

❓ What level of protection is NIJ Level IIIA?

NIJ Level IIIA is the highest standard for soft armor and ballistic helmets. It means the helmet can stop:

.357 SIG FMJ
.44 Magnum SJHP
9mm FMJ
Other common handgun threats and fragmentation

This level is ideal for law enforcement, SWAT teams, and military operations where rifle fire is not the primary threat.

❓ Do bullet proof helmets really work in real life?

Yes. There are countless documented cases of soldiers, police officers, and journalists whose ballistic helmets saved their lives, either by stopping a round or deflecting it at an angle. Modern helmets' curved design and materials are engineered to reduce impact and redirect energy away from the skull.

❓ What is the difference between PASGT, MICH, and FAST helmets?

PASGT (Personnel Armor System for Ground Troops): Older model, full coverage, heavier.
MICH/ACH (Modular Integrated Communications Helmet): Streamlined design, better for comms gear.
FAST (Future Assault Shell Technology): High-cut, lightweight, modular for special ops—great for attaching night vision, lights, and headsets.

❓ How do I choose the right bullet proof helmet?

Key factors include:

Threat level in your environment
Helmet weight (lighter is better for long missions)
Accessory compatibility (rails, NVG mounts, etc.)
Fit and comfort (adjustable padding is a must)

If you’re unsure, contact SecurityProUSA for a custom recommendation based on your specific use case.

❓ How long does a bullet proof helmet last?

Most helmets have a shelf life of 5 to 7 years, depending on material and usage. Exposure to heat, sunlight, moisture, and impacts can degrade performance. Always inspect your helmet regularly and follow manufacturer guidelines for replacement.

❓ Are SecurityProUSA helmets NIJ-certified?

Yes. All helmets sold by SecurityProUSA are tested and rated to meet or exceed NIJ standards, and many are also tested to military specs. They work with trusted manufacturers and offer full certification documentation upon request.

❓ Can civilians buy bullet proof helmets?

Yes. In most U.S. states, it is legal for civilians to own and purchase bullet proof helmets, as long as they’re not convicted felons. However, exporting ballistic gear may require ITAR or EAR compliance—so always check the rules if you’re shipping internationally.
