The M39 20mm revolver cannon was a Cold War-era aircraft gun developed by the U.S. for use in high-speed fighter jets, most notably the Northrop F-5 Freedom Fighter and early F-86 Sabre variants. It was based on the German Mauser MK 213 revolver cannon concept and optimized for American aircraft with increased reliability, a faster rate of fire (~1,500 RPM), and reduced recoil.
The cartridge ejection chute was a critical component of the M39's ammunition handling system. Installed in the aircraft's gun bay, the chute guided spent shell casings from the rear of the cannon and directed them safely away. This part was essential to ensure uninterrupted fire and prevented casing jams or damage within the confined space of a jet aircraft's fuselage.
Don't miss the chance to own this authentic U.S. Air Force M39 20mm cannon ejection chute, a rare and hard-to-source part tied to Cold War aircraft history. Light surface rust can be sandblasted and re-parkerized or preserved as-is for historic authenticity.
