Overview

E.R. Amantino is a Brazilian firearms manufacturer based in Veranópolis, in the state of Rio Grande do Sul. The company is also widely associated with the Boito name, which appears on its firearms and related products. Its origins date to 1955, when João Boito, an Italian blacksmith living in Brazil who had produced handmade shotguns and other metal goods, entered into a business partnership with local businessman Elias Ruas Amantino. Their venture, established as E.R. Amantino & Cia Ltda., initially concentrated on single- and double-barrel shotguns intended primarily for hunting. The company’s early development combined traditional metalworking with progressively more organized manufacturing. In 1962, E.R. Amantino introduced its first coach gun model, marking an important expansion of its product range beyond basic hunting shotguns. In 1977, it established Microvera, a subsidiary and specialized production facility focused on metal processing and microfusion. Microvera was created to manufacture components for Boito firearms and custom parts for other firearms producers in the South American market, giving the business capabilities beyond final firearm assembly. E.R. Amantino later developed an international sales presence. From the mid-1970s through the 1980s, its shotguns were exported to the United States for sale under K-Mart’s private-label brand. The company’s products received criticism from some customers during that period for perceived shortcomings in quality. Despite that negative reputation among some American buyers, the business continued exporting and established a more durable international position through branded and private-label distribution. A major part of the company’s international profile comes from its double-barrel shotguns. Several Boito models have been marketed in the United States under the Stoeger brand, including the A/680, commonly associated with the Stoeger Coach Gun, and the Miura II, associated with the Stoeger Condor. This arrangement helped connect E.R. Amantino’s Brazilian manufacturing base with a recognized international firearms distribution network. The company’s catalog extends beyond double-barrel guns. It includes single-barrel and pump-action shotguns, shooting and hunting accessories, automated clay-pigeon throwers, and apparel. Listed firearm families include the A/681, Double Defense, Miura I, ERA 2001, Over Defense, Reuna, B300, Pistol, and Pump models, with configurations spanning several shotgun gauges. Product availability and branding vary by market. Since 2013, E.R. Amantino has also served as the official Brazilian representative of the Italian firearms manufacturer Benelli. This representation complements, rather than replaces, the company’s own manufacturing activities. E.R. Amantino has been described as exporting approximately 70 percent of its production, with products reaching the United States, Australia, Canada, New Zealand, South Africa, Argentina, and other countries. Its products have been reported as available in more than 24 countries, making the company an internationally oriented but comparatively specialized firearms manufacturer.

History

E.R. Amantino was founded in 1955 in Veranópolis, Rio Grande do Sul, by João Boito and Elias Ruas Amantino. Boito was an Italian blacksmith settled in Brazil who had experience making handmade shotguns, while Amantino was a local businessman. Their partnership created E.R. Amantino & Cia Ltda., initially focused on manufacturing single- and double-barrel shotguns for hunting. The company introduced its first coach gun in 1962. This product milestone reflected its effort to broaden its shotgun portfolio and establish a recognizable manufacturing identity. During the 1970s, E.R. Amantino expanded its industrial base. In 1977, it founded Microvera, a facility specializing in metal processing and microfusion. Microvera supplied components for Boito firearms and also produced custom parts for other firearms businesses in South America. E.R. Amantino began developing export channels in the United States during the middle of the 1970s and continued this activity into the 1980s. Some shotguns were sold through K-Mart under the retailer’s brand rather than exclusively under the Boito name. The products attracted criticism from some customers who considered their quality inadequate. Nevertheless, the company maintained its international activity and later built a broader export network. The Boito product range became especially visible overseas through double-barrel shotguns. In the United States, several of these firearms were distributed under the Stoeger brand. The A/680 became associated with the Stoeger Coach Gun, while the Miura II became associated with the Stoeger Condor. Other models included the A/681, Double Defense, Miura I, ERA 2001, and Over Defense. The company also produced single-barrel models such as the Reuna and B300, a .410-gauge pistol configuration, and a pump-action shotgun. Beyond firearms, the company’s catalog has included accessories for hunting and sport shooting, automated clay-pigeon throwers, and apparel. Its manufacturing and distribution activities therefore cover both guns and related shooting equipment. In 2013, E.R. Amantino became the official representative of Benelli in Brazil. This gave the company a role not only as a domestic firearms manufacturer but also as a local representative for an established Italian firearms maker. E.R. Amantino has been described as exporting roughly 70 percent of its production to markets including the United States, Australia, Canada, New Zealand, South Africa, and Argentina. Its products have been reported as available in more than 24 countries, although the supplied reference material does not provide a current corporate website, ownership structure, financial data, or named present-day executives.
