This video details the experimental British conversion of the M1 Garand to select-fire capability in 1939. Expert Jonathan Ferguson explains the historical context, the 'YSL' nickname, and the significant mechanical modifications required, including milling the receiver and adding a disconnector. Trial results indicated extreme difficulty in controlling automatic fire, leading to the project's discontinuation.

Quick Summary

In 1939, Britain experimented with a fully automatic M1 Garand, nicknamed 'YSL' (Yankee Self-Loader), as an early 'light automatic rifle.' However, trials showed extreme muzzle climb made it nearly uncontrollable, with shooters unable to keep more than 2-3 rounds on target at 50 yards.

Frequently Asked Questions

What was the purpose of the British experimental Auto-Garand?

In 1939, Britain tested an experimental fully automatic M1 Garand, nicknamed 'YSL' (Yankee Self-Loader), as an early attempt at a 'light automatic rifle' concept, predating later designs like the M14 and EM-2.

Why was the British Auto-Garand conversion unsuccessful?

Trials at Hythe revealed the rifle was nearly uncontrollable in automatic mode. Even highly trained individuals struggled to keep more than 2-3 rounds on a large target at 50 yards due to extreme muzzle climb.

What mechanical modifications were made to the experimental Auto-Garand?

The receiver was milled out to accommodate a select-fire mechanism and an additional disconnector. A distinctive steel plate was added to the right side of the receiver to support these internal changes.

What does the 'YSL' nickname for the M1 Garand signify?

'YSL' was a British euphemistic nickname for the M1 Garand during its 1939 trials, standing for 'Yankee Self-Loader.' This reflected a blend of respect for the American design and typical British dry humor.
