The Italian army adopted the Beretta BM59, basically an M1 Garand chambered for 7.62×51mm NATO capable of select fire. It was about as successful as all the other select fire battle rifles adopted around the world (not very). From Wikipedia:

After World War II, Italy adopted the US-designed M1 Garand rifle in .30-06 (7.62×63mm) and also manufactured it under license. This semi-automatic rifle proved itself well during WWII, but in the late 1950s it was considered outdated and obsolete. The Italian military wanted a new rifle chambered for the NATO-standard 7.62×51mm.

Beretta designed the BM59, which was essentially a rechambered M1 fitted with a removable 20-round magazine, folding bipod and flash suppressor/grenade launcher. The BM59 is capable of selective fire.
