Were the facility codes such as the Anniston BA4 ect. used after the 1960's receiver etchings ?? If so I would suppose that these were, for the most part, rifles being overhauled to be shipped overseas as some form of foreign aid or in some cases , eventually, turned over to the DCM. The U.S. military, other than some reserve and N.G. units, were no longer using the M1rifle. Who was it that was reimbursing the facilitys, in that they are government owned ?? I wish I never thought about this as now I am racking my brain trying to figure this out when I should be getting some sleep.
