About the Boito BSA 5T 84

The Boito BSA 5T is a pump-action shotgun chambered in 12 gauge, manufactured in Rio Grande do Sul, Brazil. It is a licensed-production shotgun built on the proven Mossberg 500 pattern, featuring a lightweight aluminum-alloy receiver, dual action bars, a tubular magazine holding five 2.75-inch shells, exchangeable choke tubes, and three-dot fiber-optic sights. Offered in a range of barrel lengths for hunting, sport, and home-defense use, it is valued in South American and export markets as an affordable, durable repeating shotgun with broad Mossberg 500 parts compatibility.

Boito is one of Brazil's best-known shotgun makers, long associated with affordable break-action and pump-action smoothbores widely used by rural hunters and farmers across South America.
