Browning .303 (British) Aircraft barrel (4 pieces)

The Browning .303 was the standard gun used on British aircraft during the 1930s and Second World War. It was adopted by the Royal Air Force (RAF) and manufactured under license by Vickers Armstrong and BSA. The design was based on the 1930 Pattern belt-fed Colt-Browning machine gun with a few minor modifications. The muzzle extension was prone to fouling from the cordite-based ammunition and the RAF redesigned the muzzle extension with chrome plating it to make the surface smoother and cooling fins were also added.
