Byrna FAQ

No. The Byrna launcher is a non-lethal device, and in most states, it can be purchased without a permit or background check. However, certain jurisdictions may have specific regulations, so always verify your local laws.

No. Byrna launchers are powered by compressed CO₂ cartridges, similar to a paintball or airsoft gun, and are not classified as firearms by the ATF. That means you can legally own one without a firearm permit in most states.

Check individual airline and TSA regulations before traveling. Many domestic airlines allow an unloaded Byrna launcher in checked luggage, similar to paintball or airsoft guns.

CO₂ cartridges and self-defense projectiles are generally not permitted on flights. We recommend shipping these items to your destination ahead of time to avoid issues with airline security.

The Byrna is available in several colors, including Safety Orange, to help distinguish it from a firearm. It is intended strictly for self-defense and should never be drawn in the presence of law enforcement or armed security personnel.

Use of a Byrna offensively or in furtherance of a crime is illegal and may result in civil and criminal penalties. Always handle your launcher responsibly and never point it at anyone except in lawful self-defense.

Byrna products are legal in all 50 states, but some local or state regulations may restrict the use of chemical irritant rounds. We recommend checking your local laws to confirm what types of projectiles are allowed where you live or travel.

A Byrna launcher is a less-lethal weapon that fires chemical irritant or kinetic projectiles using compressed CO₂—not gunpowder. It’s designed to stop a threat safely without deadly force, and it can be owned without a firearm license in most areas.

Byrna offers three main projectile types:

• Pepper / Chemical Rounds – Contain irritant powder for self-defense.
• Kinetic Rounds – Hard plastic impact rounds for practice or defense.
• Inert Rounds – Non-active rounds for training or target shooting.

Always use genuine Byrna projectiles to ensure performance and maintain your warranty.

Each standard 8-gram CO₂ cartridge provides about 15–20 shots, depending on temperature, projectile type, and launcher model. Always replace the cartridge when performance begins to drop.

Most Byrna launchers—including the Byrna SD, LE, and CL—use 8-gram CO₂ cartridges. Always check your model’s manual before use. Larger rifles like the Byrna Mission 4 or TCR may require different cartridges.

Unopened CO₂ cartridges have an indefinite shelf life. Once pierced, they should be replaced after use or if left unused for extended periods to avoid pressure loss.

In most states, yes. However, concealed carry laws for less-lethal devices vary by state and jurisdiction. Always check your local regulations before carrying your Byrna in public.

The typical effective range is up to 60 feet (approximately 20 yards), depending on model and projectile type. Byrna launchers are designed for close-to-medium-range self-defense situations.

Store your Byrna unloaded, in a cool, dry location, and do not leave a pierced CO₂ cartridge installed for long periods. Keep O-rings clean and lubricated with Byrna-approved maintenance products.
