I have one of the older Rock Island Armory model 1903. Serial number below 80,000. I have been told that the bolt may possiblly be brittle and am looking for another bolt to replace it with. Any help in here?
Just thought I should correct myself before I make myself out to look like a moron.
The respective numbers on older Springfield model 1903's are those made at Springfield Armory with numbers below 800,000 and Rock Island Armory below 285,000 + don't remember the exact number on the Rock Island Armory serial numbers.
Anyway I have one that has a potentially brittle bolt. And I would like some information on where I may find a replacement for it.
Mike is right. It's the whole receiver that's brittle on the low number Springfields. See Hatcher's Notebook, Chapter IX, Receiver Steels and Heat Treatment. Rock Island numbers after 285,507 and Springfield Armory numbers after 800,000 are OK, with a few exceptions. General Hatcher notes that a few Springfield Amoury receivers got set aside and were later issued with 800,000+ numbers. #801,548 blew up.
