I recently bought these as a lot and I am looking for more information from some of these experts here. On what rifle were these used as there is no lug? In what era were these produced? Is there any info available on the various manufacturers? Many thanks!
The M5 was adopted in 1953, as stated above for the M1 Garand. The small stud sticking out of the guard fits into the end of the gas tube underneath the barrel of the rifle so does not have the Muzzle ring, that would fit over the end of the barrel. The shape of the blade started with the M3 Trench knife, then the same blade shape was used for the M4 bayonet for the M1/M2 carbine. The M5 for the Garand, the M6 for the M14 and finally for the M7 bayonet for the M16. John
There were five manufacturers. Utica, Imperial, Aerial, J&D Tool Co., and Milpar. Utica is the rarest maker. The M5 came first, which was followed by the M5A1, with had a modified and improved latch/release lever. J&D Tool Co. and Aerial Cutlery marked their later bayonet M-1, but it is still an M5A1.
