Man Hours for Production/1941/M1 Garand

Nowadays if you were spending 45 man hours on a rifle you'd go bankrupt and will have to close down. 
45 Hours Times 15$ a hour (For a CNC Machine "Operator") = 675$ in Labour costs.
Now what if they were a skilled machinist then you would have.
45 Hours Times 40$ a hour = 1800$ In Labour
This is how I'd make the M1 myself in todays world. (Using ether a billet of steel or a forging then finial machining what I'm thinking my my head would work) Assuming I wanted to save every cent I could and I was Springfield Armoury gearing up which war production.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1) Have a CNC machine set up just to machine the front of the reciver where the barrel is attached. (This is to allow you to attach it right to the 2nd CNC mill where you machine the rest of the reciver)
2) Machine on a 4 Axis (3 axis + turn table) the whole reciever clamping the trun table to the barrel area of the reciever to it so the machine can do the whole reciver at one time.
3) Hammer forge the barrel. (Its expensive equipment I read but they can produce alot of barrels quickly (1 barrel in 3 minutes))
4) Use Automated "Highspeed" Chipless machining (hammer forging, stamping, rolling etc) to make all the small parts you can for the rifle. (From what I've read the M1 used alot of stampings anyways shouldnt have too much of a problem).
5) Outsource the springs to a shop that makes springs. (You "could" make them but a spring shop would be better equiped and will be able to do it better.)
6) Any part that cannot be made/adapted for highspeed chipless machining should be turned on CNC Lathes or Mills to increase production and decrease the amount of skilled workers you'd need.

My thoughts on this anyways I think my idea's would work to cut as much time as possible. As well as to be able to use as many workers you have avalible to you without worrying about their education level in machining.
