Has anyone ever seen or heard of an M-1 Carbine 22 caliber conversion? It's not the reproduction available new today but a WWII surplus M-1 with a 22 caliber barrel liner and a 22 caliber magazine placed inside of the original 30 caliber magazine. I think I heard it was done by someone named Williams, not David Williams I don't think. Asking for a friend.
Hi Tom, could this be referring to the 22 Spitfire? Melvin Johnson designed a necked down 30 carbine to 22 caliber. He replaced the barrel to 22 caliber. He's the Johnson that invented the Johnson Rifle that gave John Garand a run for his money, regards, Mike
