When rifles were in short supply during World War I, the US military adapted the design of Enfield Model of 1917 for .30-06 ammunition and these rifles were produced for field use by American companies like Winchester. The M1917 has a longer, heavier-weight barrel than the 1903 Springfield, and combined with a longer sighting plane, proved generally more accurate at long distances. The rifle was designed with a rear receiver aperture sight, protected by sturdy ears, a design that proved to be faster and more accurate than the typical mid-barrel sight offered at the time. The rifle maintains the British cock-on-closing feature, in which the bolt's mainspring is loaded and the rifle cocked as part of the return stroke of the bolt, which aided rapid fire. The bolt handle on the M1917 recesses into a notch in the receiver, which serves as a emergency locking lug in the event of failure of the frontal locking lugs, a design that has since been adopted by many modern manufacturers. This sporterized rifle's wood and metal are in fair condition and its bore is in good condition.
