jim c 351 Posted January 10, 2022 Report Share Posted January 10, 2022 Nothing on the M1 bolt was nickeled, including the bolt. The bolt was left in the white.Jim C 1 Link to comment Share on other sites More sharing options...
Rabbit57 Posted January 10, 2022 Author Report Share Posted January 10, 2022 Jim C, thanks, I did not know that. I saw a picture in a book that described the “bright nickel bolt”, and I took it literally. Link to comment Share on other sites More sharing options...
StrangeRanger Posted January 10, 2022 Report Share Posted January 10, 2022 Probably refers to a nickel alloy steel. Adding small amounts of nickel to steel increases its impact resistance Link to comment Share on other sites More sharing options...
