All that is needed to fly with gun magazines is a bit of paperwork and the appropriate packing materials.
With just a few simple steps, you can ensure that your gun magazines are properly packed and ready for transport. First, you’ll need to declare the items to the airline. You can do this at check-in or the gate. When declaring firearm magazines, be sure to have documentation that outlines ownership of the firearms as well as registration information for the ammunition. This will usually take the form of a firearms license or permit.
Next, you’ll need to pack your gun magazines in a sturdy container. They must be securely packed so that they don’t shift during transport. A good rule of thumb is to pack them in a case that is specifically designed for gun magazines. These cases are typically made of hard plastic and have foam inserts that cushion and protect the magazines.
When packing your gun magazines, it’s also important to keep in mind the TSA’s 3-1-1 rule. This rule states that you can bring a quart-sized bag of liquids, gels, and aerosols in your carry-on bag. Each item must be 3.4 ounces (100 milliliters) or less and must be able to fit in a single, clear, quart-sized bag.
