The M1 Carbine was developed for United States troops in the early 1940s and became one of the most produced American military firearms of the Second World War. Designed as a lighter alternative to the M1 Garand for support troops, it later saw service in Korea and Vietnam. Its distinctive firing sound has been recorded for films, documentaries and games for decades. Online, creators reuse clean carbine shots as a stock gunfire effect for edits, machinima and soundboards where a period-correct rifle sound is needed instead of a modern automatic weapon.
