20mm Mk7 Mod 1 Disintegrating Metallic Links- Parkerized Steel.
See more information below...
Complete your aviation ordnance collection with authentic 20mm Mk7 Mod 1 Disintegrating Metallic Links, precision-manufactured from parkerized steel and historically used with the 20mm M61 Vulcan rotary cannon. These links are designed to connect 20×102mm cartridges into a reliable, aircraft-ready feed belt for the United States military’s most iconic high-rate-of-fire cannon system.
The Mk7 Mod 1 link emerged during the Cold War era as the U.S. military refined its aircraft armament systems. As jet fighters evolved and demanded higher firepower with uncompromising reliability, the M61 Vulcan—a six-barrel, electrically driven Gatling cannon—became the standard gun system across numerous Air Force and Navy aircraft beginning in the late 1950s.
To support the Vulcan’s extreme firing rates and rotational stresses, ordnance designers developed improved linking systems, including the Mk7 Mod 1. These links offered:
Enhanced strength under high mechanical load
Smooth disintegration during firing
Reliable retention of 20mm cartridges during vibration and maneuvering
The Mk7 Mod 1 is historically associated with platforms such as the F-4 Phantom II, F-14 Tomcat, F-15 Eagle, F-16 Fighting Falcon, and various naval aircraft and CIWS developmental programs. As a result, these links became a widely used and instantly recognizable component of U.S. 20mm aircraft ammunition belts.
These parkerized steel links are ideal for:
Aviation and military history collectors
Display-grade inert belts
Museum exhibits
Restoration projects
Cold War and modern ordnance collections
Each link represents decades of U.S. aircraft weapons history and is perfect for pairing with inert 20×102mm projectiles or for creating period-correct display belts.
