I've seen many references regarding using silver solder to attach parts to receivers and barrels. In the Garand/BM59 realm this usually refers to adding a stripper clip guide. I don't particularly want to add a stripper clip guide to my BM59, but I'm just curious. Does this method of attaching parts affect the heat treatment or hardness of a Garand receiver? Are particular solders or methods used to bypass this problem?

Thanks-- D.
