Whats a bolt stamped with either "D dot R", "DK3" or "DE" mean? couldnt find any numbers they have cross flags but thats it besides the letters

It would hep if you knew what gun, and what type.

From "crossed flags" I'm assuming you have an australian L1A1 and the letters are steel batch codes - if a defect came out in the metallurgy they could trace it to the origin and know what other bolts to recall.

DR-DT 1964

DK-DN 1963

DE-DG 1960 (no DF)
