It's important to know that due to state and local laws, there are certain restrictions for various products.
It's up to you to research and comply with the laws in your state, county, and city.
If you live in a state or city where air guns are treated as firearms you may be able to take advantage of our FFL special program.
U.S. federal law requires that all airsoft guns are sold with a 1/4-inch blaze orange muzzle or an orange flash hider to avoid the guns being mistaken for firearms.
