This weapon, designed by Breda in 1930, and had several flaws in the design:
1: Fragile usage with bad lubrification
2: Too fragile 20 magazines
3: High building costs due to extreme mechanical perfection
4: Slow Rate Of Fire
This was an automatic weapon and used a direct recoil system, so that bolt and barrel recoiled in different spaces.
The cooler system was by air, but after some hundreds of rounds the barrel had to be changed. This weapon was produced
from 1930-1937.
