As the already worn tooling began to wear beyond use Remington began seeking Army approval for a continuously increasing number of changes and simplifications to both speed up manufacture and improve performance. The very early rifles are almost indistinguishable from 1919-made Rock Island rifles. Remington began production of the M1903 in September 1941, at serial number 3,000,000, using old tooling from the Rock Island Arsenal which had been in storage since 1919. World War II saw the new production of the Springfield at private manufacturers such as the Remington Arms and Smith-Corona Typewriter companies. It remains popular as a civilian firearm, historical collector's piece, a competitive shooting rifle, and as a military drill rifle. It also remained in service as a sniper rifle during World War II, the Korean War, and even in the early stages of the Vietnam War.

Using these barrel codes to date a shotgun is somewhat unreliable, as shotgun barrels are often interchanged at random. Using barrel codes (such as those listed above) to date the manufacture are reliable on Remington rifles, as the company rarely changed barrels on a customer’s rifle.
