Picking it up, USMC with hatcher hole. stippled butt, etched bolt and unmarked stock. Could not be happier! Will pic when received. Sorry, Rock Island 367XXX. Safe to shoot!     

im interested in this thread.  i know someone with a 1903.  when you say "safe to shoot" does that imply that some aren't?  how can you tell

There are high and low serial number ranges for Springfield Armory and Rock Island Arsenal made 1903 rifles. This does not apply to Remington made 1903 rifles or 1903-A3 rifles, nor Smith Corona 1903-A3s. They discovered that some of the receivers they were manufacturing were not properly heat treated, and changed the process.

 

For SA, the switch happened around the 800,000 mark, and RIA changed at serial number 285,507. 1903s above those serial numbers are considered safe to shoot.
