This video explores a rare, fully automatic M1 Garand prototype tested by the British in 1939. Jonathan Ferguson details the 'gas trap' variant and its experimental conversion for automatic fire, highlighting significant recoil and accuracy issues that rendered it impractical. The trials ultimately reinforced the concept of the semi-automatic rifle for average soldiers.

Quick Summary

In 1939, Britain tested an experimental fully automatic M1 Garand, nicknamed 'YSL' ('Yankee Self-Loader'). Despite modifications for select-fire, trials revealed extreme muzzle climb made it uncontrollable, with shooters unable to keep more than 2-3 rounds on target at 50 yards.
