I've read in some places that it's advantageous to have a spare bolt, among other things, for M14 / M1A's. Scott Duff recommends this, as well as having this spare bolt fit the headspacing of the individual rifle.
My question is how is this feat accomplished? More specifically, what needs to be done on the bolt to make the headspace match the existing rifle? Would this involve filing the lip of the bolt face in some fashion, or maybe the cam on the inner side of the bolt?
TIA.
