What it is, and why it matters

The FARA 83 is a select-fire assault rifle chambered in 5.56x45mm NATO, produced by Fabrica Militar de Armas Portatiles Domingo Matheu since 1983. This Argentine-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 30-round magazine capacity, this assault rifle offers generous firepower for duty use and home defense. The 17.8-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. At 3950g (139.3 oz), this is a substantial firearm whose weight contributes to reduced felt recoil and enhanced stability during precision shooting. The steel frame provides a solid, premium feel with the durability to withstand decades of regular use and thousands of rounds. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.

The FARA 83 was born from Argentina's post-Falklands War determination to modernize its military with domestically produced weapons, reducing dependence on foreign suppliers who had imposed arms embargoes during the conflict. Designed by Ing. Enrique Chichizola - an Argentine engineer, not to be confused with the Italian Beretta family - the rifle represented a significant achievement in Latin American small arms design. However, Argentina's crushing economic crisis of the 1980s, including hyperinflation that would eventually reach 3,000% annually, killed the program before it could reach full production. Today, surviving FARA 83 rifles are prized collector's items, with most of the approximately 1,200 produced still in Argentine military storage.

Development of the FARA 83 began in 1975 under the classified program 'Proyecto Codigo 10.0187', with the first prototype completed in mid-1979 as the FAA 81 (Fusil Automatico Argentino). The design drew influences from the FN FAL and Israeli Galil, incorporating an HK-style charging handle and a synthetic folding stock with an internal compartment for cleaning tools. The barrel features six right-hand grooves with a 1:9 inch (229mm) twist rate, optimized for both M193 (55-grain) and SS109/M855 (62-grain) ammunition. Initially the rifle used proprietary steel magazines, but STANAG compatibility was planned for later production. An optional folding bipod weighing 400g was available. Approximately 50 pre-production examples were built during 1982-1983, followed by roughly 1,143 additional rifles before budget cuts halted manufacturing in 1986. The Argentine Army ultimately retained its FN FAL variants in 7.62mm NATO. Later stock iterations replaced the synthetic folding design with PARA-FAL metal tubular stocks fitted with plastic cheek rests.
