Inside the KPV 14.5mm - Why This Cold War Cannon Behaves Like a Rifle

Description:

This video is an educational engineering breakdown of the KPV 14.5mm heavy machine gun, created for historical, mechanical and technical understanding. No combat footage. No promotion. Just engineering. The KPV 14.5mm is one of the most extreme weapons ever designed: a machine gun firing a round closer to artillery than small arms… yet somehow it behaves with the control of a rifle. In this video, I open up the system, the recoil timing, the moving parts, the feed cycle, the short-recoil choreography; and show how Soviet engineers turned raw violence into mechanical rhythm. You’ll see why the KPV doesn’t fight recoil, it reuses it, how the barrel and bolt move together in perfect timing, and why this 14.5mm platform became the backbone of Soviet armored vehicles and AA mounts for decades. If you enjoy mechanical breakdowns, engineering deep dives, and how weapons actually work, you’re going to love this one.
