prepare, thank you for looking into this and reporting back.
Assuming what H&M says is true, now the trick is to find out which bolts have been nitrided by them using this process. My understanding (which could be wrong) is that there are not a lot of companies that do large scale nitriding on firearms parts in the U.S.
