sentences:  After World War II, Italy adopted the US-designed M1 Garand rifle in .30-06 Springfield (7.62×63mm) and also manufactured it under license.This semi-automatic rifle proved itself well during World War II, but in the late 1950s it was considered outdated and obsolete and the Italian military also wanted a new rifle chambered for the NATO-standard 7.62×51mm round.To meet these requirements, Beretta designed the BM 59, which was essentially a rechambered M1 fitted with a removable 20-round magazine, folding bipod and a combined muzzle brake/flash suppressor/rifle grenade launcher.
