  1. I understand how an M1 Garand works, some of the gas from the shot cartridge is bled off through the barrel to the gas port which pushes a piston/sprung op rod, which ejects the spent cartridge then feeds a fresh bullet from the en bloc clip. How does the system work with the Johnson 1941 Rifle?
  2. Thanks Joseph, That's just the kind of information I was after. Are there any published books available that document the process?
  3. I have done a little more research on the 1941 ID page here, and it appears the receiver was made from 2 parts welded together. Action milled or forged, and the barrel shroud made from heavy gauge sheet steel. My copy of Johnson Rifles and Machine Guns, 1968, ed Don B McClean, page 14, shows a full length receiver, set up on milling machine. I'm not sure if this is just a publicity photo with a finished receiver on the machine, or whether it is a true reflection of the actual manufacturing process? I thought one of the advantages over the Garand was that it was easier to manufacture the Johnson? This process sounds more complicated than the forge/finish milling of a Garand receiver, which is much smaller due to not having an integral barrel shroud.
  4. Does anybody know how the Johnson receiver was made: milled, or forged,or cast, or welded, or some combination of methods? It looks like it would take a whacking great bar of steel if you wanted to mill one out, with most of it ending up as waste. Does anyone know what type of steel was used? Was it case hardened or tempered right through? Many thanks.
