Springfield 1903 received a Feed Ramp to fix reliability, what year? #gun

the feed ramp was added to the Springfield Model 1903 rifle in response to issues with feeding and reliability. The original design of the 1903 used a single-stack, flush-fit magazine that did not incorporate a feed ramp, and this caused some problems with reliable feeding, particularly when using pointed or spitzer-shaped bullets.

To address this issue, the design was revised in 1908 to incorporate a new magazine cut-off that allowed the rifle to be loaded with a single round while keeping the remaining rounds in the magazine. This design change allowed for the addition of a feed ramp, which helped guide the cartridges into the chamber more reliably.

The new design was known as the Model 1903 Mark I, and it included the magazine cut-off and feed ramp, as well as other minor improvements. Subsequent models of the Springfield rifle, such as the Model 1903A3, also included a feed ramp and other modifications to improve feeding and reliability.
