M60: Its Purpose, Mechanics, and Development

Published on February 25, 2022
Duration: 28:28

The M60, nicknamed 'The Pig,' was developed as a versatile US military machine gun, merging German FG42 operating systems with MG42 belt-feed mechanisms. Despite its adoption in 1957 to simplify logistics, early prototypes faced significant mechanical issues like weak firing pins and stellite barrel warping. While designed for full-auto fire with a push-through link system, later durability problems led to its replacement by the M240.

Quick Summary

The M60 machine gun, nicknamed 'The Pig,' was developed by merging German FG42 operating systems with MG42 belt-feed mechanisms. Adopted in 1957, it aimed to simplify US military logistics by replacing several firearms. Despite its role, it faced early mechanical flaws and later durability issues.

Frequently Asked Questions

What was the primary purpose of the M60 machine gun?

The M60 was adopted in 1957 to serve as a versatile, primary US military weapon, intended to replace multiple existing firearms like the M1 Garand, BAR, and various Browning machine guns, thereby simplifying logistics.

What German machine gun designs influenced the M60?

The M60's design was heavily influenced by German concepts. It combined the operating system of the FG42 rifle with the belt-feed mechanism found in the MG42 machine gun.

What were some common mechanical issues with the M60?

Early M60s suffered from weak firing pins leading to out-of-battery discharges and extraction failures caused by stellite barrel liners warping under heat. A notable flaw allowed the gas piston to be installed backward.

How does the M60's ammunition feed system work?

The M60 uses a 'push-through' system with disintegrating metallic links (M13 links) for its 7.62mm NATO rounds. The bolt pushes the round directly into the chamber during operation.
