The Byrna launcher is a gas-powered personal security device and is not regulated as a firearm under federal law but may be subject to state and local regulations related to use and carrying. Always check your local laws before carrying a Byrna launcher outside of your home.

AIRLINE TRAVEL: While the Byrna is not considered a firearm under United States federal law, it may be considered a firearm or its possession may be otherwise prohibited in other countries. When traveling domestically with your Byrna launcher always check local regulation of gas-powered “air guns” at your points of departure and arrival as well as individual airline regulations. If you are traveling with chemical irritant projectiles also check local laws on tear gas weapons and pepper sprays. The Byrna may not be carried on your person through airport security checkpoints, nor may it be packed in “carry-on” baggage. Subject to local law and individual airline regulations the Byrna may be transported, unloaded, in checked baggage. A locked box may be required in some jurisdictions.

You'll most likely need to leave the pepper balls and Max projectiles home if traveling by air.

Fore example, from Delta airlines site:

While firearms and ammunition can be checked as sporting equipment with strict guidelines, there are a few exceptions as required by law. Review the regulations before you bring anything potentially hazardous to the airport.


We allow small arms ammunition, in quantities not exceeding 11 lbs. (5 kg) per person, as checked-baggage only. The weapon must be securely boxed and intended for that person's own use. More than one passenger may not combine quantities into one package.

You are responsible for knowledge of and compliance with all Federal, State or local laws regarding the possession and transportation of firearms. For more information about this regulation you can visit the TSA website, opens in a new window.

Note: Gunpowder (e.g., Pyrodex, black powder, mace, pepper spray and tear gas) is never permitted.

CO2 CYLINDERS: Never leave a CO2 cylinder, punctured or un-punctured, in your Byrna when you travel. FAA regulations permit up to four (4) cylinders (less than 28g each) containing nonflammable gas, but individual airlines and the TSA may further regulate or restrict. Always check current rules before traveling as laws may change.

TRANSPORTING YOUR BYRNA IN A MOTOR VEHICLE: Some state and local laws regulate the transportation of gas-powered “air guns” and self-defense projectiles in motor vehicles. Always check local regulations in areas you intend to drive.
