Costa Rican Breda PG: The First Burst-Fire Rifle
The Breda PG, an early Italian select-fire rifle, was produced for Costa Rica in 7mm Mauser with a unique 4-round burst feature. It fires from an open bolt and utilizes a complex dual-ratchet mechanism for its burst mode, which has limitations in accuracy after switching fire modes. Despite its innovative design, the rifle's complexity and quirks likely hindered widespread adoption.
