Quick question. I've been collecting parts kits and build tools for years now and am finally getting around to getting started. One question is on heat treating. I don't have a kiln so mapp torch is my method for heat treating. I've noticed that most tutorials suggest after the initial heat and quench to reheat to about 750 degrees and allow to cool. Ak-builder suggests baking in the oven at 400 degrees for an hour for the 2nd stage. Is one method better or will both work?
