Years ago... It is called 'spot annealing' a softening of the metal only where to be drilled. This is an easy one for a qualified gunplumber.

Here is some information about drilling and tapping the 03A3 wrrtitten by Harold McFarland who was a premier gunsmith during the era when many 03A3's were being converted into sporters. Hope this is of some value.
