Gunsmithing Another M40 conversion question

I finally have the money to spare to start this project and was going back through the complete list of the items I needed.

It pretty much sounds like if I use a R700, that the entire gun will pretty much be replaced minus the action on the gun. Is that true, and if so, could I possibly find the required parts of the gun someplace?
 
Re: Another M40 conversion question

If you can find an early Remington 700 varmint or police model in 308 with the 24 inch barrel, all you need would be the stock. But yes, if you are going the M40 route everything is probably going to be replaced.
 
Re: Another M40 conversion question

I'm actually looking to do the M40A3, which has a different barrel from the A1 and a different McMillan stock, as far as I know I think everything else is the same as the A1.
