SIG KE-7 Light Machine Gun - More Complex Than Most

Published on May 19, 2017
Duration: 17:14

This guide details the field stripping process for the SIG KE-7 Light Machine Gun, as demonstrated by Ian McCollum. It highlights the complexity of the Swiss design, including its short recoil operation and progressive trigger. The process involves separating the barrel and receiver assemblies and then further disassembling the bolt carrier group.

Quick Summary

The SIG KE-7 Light Machine Gun, designed by Gotthard End and Pal Kiraly, is noted for its complex Swiss engineering, featuring a progressive trigger for semi-auto/full-auto fire and an open-bolt operation. Its barrel replacement requires significant disassembly, making it 'easily replaceable' rather than 'quick-change'.

Frequently Asked Questions

What makes the SIG KE-7 Light Machine Gun complex?

The SIG KE-7 is complex due to its intricate Swiss machining, a progressive trigger offering semi-auto and full-auto fire, and a unique hold-open mechanism. Its short recoil system with an accelerator lever also adds to its mechanical sophistication.

How does the SIG KE-7's trigger work?

The KE-7 features a progressive trigger. A partial pull allows for semi-automatic fire, while a full, deliberate pull engages the full-automatic firing mode. It also includes a disconnect that prevents firing when the magazine is empty.

Can the SIG KE-7's barrel be changed quickly?

While the barrel can be easily replaced, the process requires significant disassembly. It's not a 'quick-change' barrel suitable for rapid replacement during combat, unlike some other machine guns designed for that purpose.

What calibers was the SIG KE-7 chambered in?

The SIG KE-7 was most commonly chambered in 8mm Mauser for contracts with China and Ethiopia. However, SIG also offered it in various other standard rifle calibers to suit different international military requirements.
