The M5 bayonet was produced by AERIAL, J & D TOOL CO., IMPERIAL, UTICA & MILPAR COL. to fit the M1 carbine. It has a shorter blade length being 6 5/8". This bayonet will fit only the M1 Garand. There is a stud on the bayonet that fits the gas cylinder lock screw on the end of the Garand Rifle; making it the only U.S. bayonet without a barrel ring on the hilt. On the Hilt is listed M5, M5-1, M5A1 and the manufacturer's name. This bayonet was not used during the Korean War, manufactured late in 1953.
