Important Listing Note: The pictures show the original packaging for reference only. The original packaging is not included. The customer will receive one 20mm Mk 12 Drive Slide Guide Pin only.
Historical Significance
The 20mm Mk 12 automatic gun was part of the U.S. Navy’s Cold War aircraft armament world. Public aircraft armament references identify the Mk 12 used in the A-4 aircraft as a fixed-mounted, gas blowback, air-cooled, electrically fired, pneumatically driven 20mm weapon with a listed rate of fire of 1,000 rounds per minute. The same reference notes that the Mk 12 used a Mk 7 feed mechanism and fed linked Mk 100-series 20mm electrically primed ammunition.
That connection gives this small guide pin added collector value. It belongs to the parts ecosystem behind a high-speed aircraft cannon system rather than a common hardware item. For collectors of U.S. Navy aircraft guns, A-4 Skyhawk armament, 20mm cannon parts, and Cold War aviation ordnance, this is a useful part-numbered reference piece.
The Mk 12 Drive Slide Guide Pin
The Drive Slide Guide Pin is a component-level part tied to the mechanical operating system of the Mk 12 cannon family. Parts like this helped support the larger movement, alignment, and function of the gun’s internal assemblies.

Why This Part Matters
The 20mm Mk 12 represents the aircraft cannon era of U.S. naval aviation, when jet aircraft relied on compact, fast-firing 20mm gun systems for close-range armament. The complete cannon depended on many important pieces, including pins, guides, slides, springs, retainers, feed parts, and drive components.
This Drive Slide Guide Pin helps preserve that support history. It is a part-numbered component with a clear NSN, making it useful for collectors who value traceable military hardware rather than unidentified surplus parts.
It pairs well with Mk 12 cannon displays, A-4 Skyhawk armament references, 20mm aircraft gun parts, Cold War naval aviation collections, and U.S. military ordnance component displays.
