Anvil 0103: M60 "Pig" maintenance, description of operation

Published on September 3, 2021
Duration: 17:35

This video provides an in-depth look at the M60 'Pig' machine gun, detailing its gas system mechanics, bolt operation, and feed mechanism. Mark Novak explains the importance of headspace, the function of disintegrating links, and demonstrates the Kendall Ordnance Linker tool. The content also touches on the weapon's historical context and the physical demands of carrying it.

Quick Summary

The M60 machine gun operates using a gas-operated, short-stroke piston system. It is an open-bolt weapon, meaning the bolt stays rearward until the trigger is pulled. Headspace is set by the barrel's fit into the receiver, and maintenance of receiver channels is crucial to prevent malfunctions.

Frequently Asked Questions

How does the M60 gas system work?

The M60 utilizes a gas-operated system with a short-stroke piston. Gases tapped from the barrel enter an expansion chamber, which cools and slows the action before pushing a piston. This piston strikes the operating rod, driving the bolt assembly rearward to eject the spent casing and chamber a new round.

What is the significance of the M60 being an open-bolt weapon?

As an open-bolt weapon, the M60's bolt remains locked to the rear on an empty chamber until the trigger is pulled. The trigger mechanism actually controls the release of the bolt and hammer, meaning if the trigger group is removed with the bolt back, the weapon could fire continuously.

How is headspace set on an M60 machine gun?

Headspace on the M60 is primarily determined by the precise fit of the barrel into the receiver. This critical dimension ensures the bolt can properly lock onto the cartridge rim for safe and reliable firing.

What is the purpose of the Kendall Ordnance Linker tool?

The Kendall Ordnance Linker Mark 1 Mod 0 is a specialized tool designed for the rapid assembly (linking) or disassembly (de-linking) of 7.62mm NATO ammunition belts. It significantly speeds up the process of preparing ammunition for machine gun use.
