Built from repurposed 20mm Hispano anti-aircraft cannon barrels, the RT-20 features a bullpup configuration and an innovative gas venting system to mitigate its substantial recoil. The description highlights the resourceful nature of Croatian wartime arms manufacturing and notes that a few RT-20s remain in service with the Croatian Police.
