Belizean laws are very restrictive and even harder to imoprt your own weapons. Certain calibers are totally illegal. There are a couple of shooting ranges in the country. The cost is $500 per permit per weapon. A single shot 20 gauge sells for over 500 BZE. 9 mil only allowed pistol caliber. 16 and 20 gauge shotgun and forget rifles altogether.
You have two kinds of licenses. Personal protection and farm use(mostly shotguns.) Anything bigger than a 9mm is classified as prohibited except shotguns of course, unless they are sawed off then they are definitely prohibited. Ammunition is not licensed but to buy ammunition one must produce a license. Personal firearm license is $75 per annum while farm license is $5 per annum. Recently they began offering licenses for up to three years. Before, one had to license every year on your birthday.
It is illegal to take firearms or ammunition into or out of Belize.
