Historical Significance
The M3, M24, M24A1, Mk12, and Mk16 20mm guns served in a wide variety of roles during and after World War II, including aircraft armament, and naval defense systems. These guns were known for their high rate of fire and combat reliability, with many variants mounted on fighters such as the F-86 Sabre, bombers, anti-aircraft emplacements, and Navy carrier-based aircraft during the Cold War era.
The gas cylinder spring plays a crucial role in regulating the weapon’s gas pressure and cycling the bolt assembly after each shot—ensuring reliability during sustained automatic fire. A worn or fatigued spring can drastically reduce function, making this original component essential for any detailed rebuild or accurate display.
