Definition
The Beretta BM 59 is an Italian gas‑operated, selective‑fire battle rifle chambered for the 7.62×51mm NATO cartridge. It was developed by Fabbrica d’Armi Pietro Beretta as an evolution of the World War II‑era M1 Garand.
Overview
Introduced in 1959, the BM 59 was designed to meet the post‑World War II demand for a modern, NATO‑standard rifle. It retained the Garand’s gas‑operated, rotating‑bolt mechanism but incorporated a detachable box magazine, selective‑fire capability, and optional accessories such as a bipod and a rifle grenade launcher. The rifle saw service with several armed forces, including Italy’s Army and Navy, as well as export customers in Latin America, the Middle East, and Africa. Production continued into the 1980s, and the design was later adapted into civilian sporting variants.
Etymology / Origin
The designation “BM 59” combines the abbreviation BM, standing for Beretta Modello (Italian for “Beretta model”), with 59, indicating the year of adoption—1959. The name reflects both the manufacturer and the rifle’s entry into service.
