also depending on who demilled the rifle for drill use you may have even more to deal with. here's what CMP does to theirs...
gas cylinder lock screw is welded to lock and gas cylinder, barrel is drilled, plugged and welded at chamber mouth. Barrel is welded to the receiver, firing pin hole is welded closed on bolt face. Rifle wear will be exhibited by worn and mixed colors of the finish; there may be some pitting on the metal parts; wood will be basically sound but may be well used with minor hairline cracks, poor fit, and many dings, scratches and gouges; wood may not match in color, type of wood or condition. Wood may be Walnut, Birch, Beech or other variety.
you may be better off just buying a service grade from CMP and not have to worry about it.
also for the record you left out a lot of information like manufacturer, condition, overall metal finish.
