I was wondering, do you need to heat treat the entire receiver for AK type rifles when using a flat to construct the receiver. I have the “Building the AKS Rifle” Video and after watching it several times I still don’t recall hearing anything about heat treating except for the bolt rails. Did I miss something here or is it not necessary to heat treat the entire receiver.
I have seen instructions from others ( not AGI) stating to heat treat the fire control holes then go back and draw down the entire receiver @ 600 degrees for 1 hour. Just thought I would ask before taking on the project, a little confused on this subject.
It is not necessary to heat treat the whole receiver. The areas that need the heat treatment are the areas where parts wear against one another. The rails definitely and around the fire control holes is not a bad idea but it is not necessary. As far as how you should heat treat depends on what kind of metal the receiver is made out of.
