Frequently Asked Questions

What is the primary function of the M60's gas system?

The M60's gas system is designed with a constant-volume expansion chamber that allows gases to cool and expand, effectively slowing down the violent action of the bolt carrier and piston for smoother operation.

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. Proper headspace is critical for safe and reliable functioning, and dirt in the receiver's linear bearings can cause issues.

What is the purpose of the Kendall Ordnance Linker Mark 1 Mod 0?

The Kendall Ordnance Linker Mark 1 Mod 0 is a specialized tool designed for the rapid assembly (linking) and disassembly (de-linking) of 7.62mm NATO ammunition belts, significantly aiding machine gunners in preparing their ammunition.

Why is the M60 nicknamed 'The Pig'?

The M60 is nicknamed 'The Pig' due to its considerable weight, which presented a significant physical burden to the soldiers who carried and operated it, especially in challenging terrain during the Vietnam War.
