Byrna HD State Restrictions and Warnings

The Byrna HD is not a firearm under federal law and is legal to own in every state in the United States except California and Minnesota. State and local laws may regulate the purchase, possession, or use of Byrna devices by prohibiting or restricting possession or use of the Byrna in certain venues, such as public areas including parks, walkways, entertainment venues, schools, or government buildings, or by certain categories of persons such as minors, felons, persons with a history of drug or alcohol dependency, or persons who have been subject to domestic abuse orders. They may also regulate where and under what circumstances it can be discharged, conditions for open or concealed carry, how it can be transported, the number of self-defense projectiles that may be owned, and the legality of accessories such as laser light attachments. Some localities may require owners of Byrna devices or projectiles to register or obtain a permit from the local police department.

The foregoing and the additional information below is intended for illustrative purposes to give you an understanding of the ways states and localities may regulate the possession or use of the Byrna but it is not exhaustive. We have not identified or analyzed every state and local law that may apply. It is your responsibility to check your state and local laws to ensure that purchase and possession of the Byrna is legal in your locality, before travelling with the Byrna, and to fully understand applicable laws relating to its ownership and use. Laws change. It is your responsibility to keep up on the laws related to ownership, possession, and use of your Byrna.


New York and Massachusetts
The Byrna HD kit and all our self-defense projectiles contain micro-pulverized pepper products. These projectiles are subject to state laws which prevent us from shipping them to New York and Massachusetts. If you are a resident of New York or Massachusetts you may provide an alternative address for shipping at check-out or the projectiles in your Byrna HD Kit and any order for self-defense projectiles will be replaced with training projectiles. Additionally, purchasers who intend to use a Byrna in New York should be aware that our Byrna Black self-defense projectiles are prohibited there, so they should only purchase our all natural OC Projectiles (Jingle Balls). We hope in the near future to be able to provide authorized dealers of our self-defense products in New York and Massachusetts.

California and Minnesota
We do not ship the Byrna HD or any self-defense projectiles to California or Minnesota because they are not currently legal to possess in those states.

Michigan, Nevada, New York, and Wisconsin:
Our Byrna Black self-defense rounds are filled with a powerful combination of 3% OC (oleoresin capsicum - a natural capaisinoid derived from chili peppers), 1.25% CS (orthochlorobenzalmalononitrile), and 0.25% PAVA (a synthetic capaisinoid). These rounds are prohibited in Michigan, Nevada, New York, and Wisconsin but permitted in all other states where we ship the Byrna HD and self-defense projectiles.

Purchasers shipping to Michigan, Nevada, and Wisconsin, and New York purchasers shipping to an address outside of the state, can buy our all natural OC projectiles, Jingle Balls, which contain 5% oleoresin capsicum and no other active ingredients. These rounds are fully compliant with those states’ laws restricting the content of self-defense pepper products. All of our self-defense projectiles are exclusively formulated for us and are designed to have an immediate debilitating effect on an attacker.

New York City and Yonkers
New York City or Yonkers prohibit the sale, possession, and use of CO2 powered launchers in those cities. If your shipping address is in the five boroughs of New York City or Yonkers please do not place an order for a ByrnaHD or any self-defense rounds as you would be in violation of those laws.

International locations, Alaska, Hawaii, and U.S. Territories
We do not currently ship any Byrna devices internationally or to Alaska, Hawaii, the United States Virgin Islands, or Puerto Rico, Guam, American Samoa, or the American Mariana Islands due to regulations that prevent us from shipping our 8 gram CO2 cartridges by air.

South Africa

Byrna HD’s are available in South Africa from Dave Sheer Guns

Minimum Age to Purchase
We do not sell to persons under 18 under any circumstances. Some localities may regulate purchase, possession and use by persons under 21. It is your responsibility to check applicable local laws before purchasing a Byrna.

By purchasing a Byrna you represent that you have checked and understand applicable laws in your state, county and local municipality, that you are at least 18 years old (21 if required in your locality), and that you are not in any category of persons prohibited from owning a gas powered weapon or self-defense pepper device. The buyer assumes all responsibility for safe and lawful storage and use of Byrna launchers, projectiles and CO2 cartridges.

Permissible Uses:

The Byrna HD is intended for use by adults for personal self-defense. It is not intended to be used as an offensive weapon. It is illegal to point it at a police officer or other law enforcement personnel acting in their professional capacity, to use it in furtherance of a crime, or to brandish it recklessly or intentionally to threaten or injure any person except where permitted in reasonable defense of person or property. While the Byrna HD is a non-lethal device, it is still a dangerous weapon and if used improperly can result in criminal and/or civil liability.

Possession or operation of the device by certain persons or in certain locations may be prohibited by applicable law. Always check state and local laws before carrying or travelling with the Byrna. See above.

The Byrna may not be “carried-on” on commercial airlines. It may be permitted in checked luggage on domestic and certain international flights subject to individual airline regulations and international, state, and local law and regulation. Before travelling always check individual airline and airport rules as well as local laws and regulations for all points of embarkation and disembarkation as well as FAA and TSA regulations, all of which are subject to change at any time.

It is the buyer’s responsibility to accept all responsibility for the use of the Byrna devices. It is important that you carefully read and understand all instructions in the product manual [insert link] before unwrapping or attempting to operate the device, including but not limited to those related to use of the safety mechanism, loading and identification of the rounds, the safe use and storage of the launcher, rounds, and CO2 cannisters, and recommendations concerning discharge and travel with your Byrna.

The Byrna launchers are not toys and should not be left without the safety on or where children can access them. Check local laws on storage of weapons, including where they may be accessed by children.

Never point a Byrna launcher at a person’s face as the projectile can cause permanent eye injury.

Never use a Byrna launcher for target practice without first taking proper precautions to protect nearby persons, animals, and property from injury either directly or from ricocheting rounds.

Protective eyewear should be worn when using the practice rounds by all persons in the area, and precautions should be taken to ensure that rounds don’t leave the target area and don’t endanger any nearby person, animal, or property, including on adjoining lots and in any public walkway or road.

Byrna self-defense projectiles contain one or more of the following: oleoresin capsaicin (“OC”), orthochlorobenzalmalononitrile ("CS") and Nonivamide (PAVA), a synthetic capsaicin. These ingredients cause skin, eye, and respiratory irritation. Handle with care!

Where possible avoid deploying self-defense projectiles in areas of intended egress.

No product is 100% effective. The functionality and effectiveness of Byrna self-defense rounds may be affected by cold weather below 32 degrees Celsius and hot temperatures above 104 degrees Fahrenheit, the nature of the surface at the point of impact, and wind conditions and air-flow patterns.

Do not store the CO2 cartridges or self-defense rounds at temperatures below those recommended by manufacturer.

For best performance the CO2 cartridge should be replaced after the discharge of two full magazines of practice projectiles, although a single cartridge may discharge up to four full magazines. After a target practice session is completed, the cartridge must be replaced before the device can be relied upon for self-defense.

The Byrna HD should be loaded with an CO2 cartridge that has not previously been used to discharge the weapon before it is used for self-defense. With an unused cartridge in place, the Byrna may be kept loaded with self-defense rounds, with its safety. Once the weapon has been discharged the CO2 cartridge will gradually lose effectiveness, and the cartridge should be replaced before the weapon can be relied upon for self-defense.

Do not use the Byrna with projectiles or CO2 cartridges sold by any other company. They may not work properly, may damage your Byrna, or may become permanently lodged in your Byrna. This may cause injury to you or persons or property in the area. Improper use in conjunction with non-Byrna products will void your warranty.
