Breda PG

The Breda PG (Italian: Presa Gas, Gas Operated) was a prototype automatic rifle manufactured by Breda.

The PG was a gas-operated rifle fed from a 20-round magazine. It was trialled by the Italian government and sold to the Costa Rican government. The Italian models were semi-auto only and chambered in 6.5×52mm Mannlicher–Carcano, while the Costa Rican models were chambered in 7x57mm Mauser and had an automatic fire mode with a four-round burst limiter. This makes the PG the world's first burst-firing automatic rifle.
